Atoms are too pocket-sized to let meaningful measurement of chemical substances. To work with meaningful amounts of substances, scientists group them into units called moles. A mole is defined every bit the number of carbon atoms in 12 grams of the isotope carbon-12,^[ane] which is roughly six.022 10 x²³ atoms. This number is called Avogadro'due south number or Avogadro's constant.^[2] This abiding is used as the number of atoms given by one mole for any substance, and the mass of 1 mole of a substance is its tooth mass.

1

Understand molar mass. Tooth mass is the mass (in grams) of one mole of a substance.^[3] Using the atomic mass of an element and multiplying information technology past the conversion gene grams per mole (g/mol), you can calculate the molar mass of that element.
ii
Find the relative atomic mass of the element. An element's relative atomic mass is the average mass, in atomic units, of a sample of all its isotopes.^[four] This information can exist found on the periodic table of elements. Locate the element and find the number underneath the symbol for the element. It will not be a whole number, but will take decimals.
- For example, for hydrogen, the relative atomic mass is 1.007; for carbon, it is 12.0107; for oxygen, information technology is 15.9994; and for chlorine, it is 35.453.

Multiply the relative atomic mass by the molar mass constant. This is defined as 0.001 kilogram per mole, or 1 gram per mole. This converts diminutive units to grams per mole, making the molar mass of hydrogen 1.007 grams per mole, of carbon 12.0107 grams per mole, of oxygen 15.9994 grams per mole, and of chlorine 35.453 grams per mole.
- Some elements are just found in molecules of two atoms or more. This means that if you lot desire to find the molar mass of elements that are composed of ii atoms, such as hydrogen, oxygen, and chlorine, so you lot'll have to observe their relative atomic masses. Multiply them by the molar mass constant, and then multiply the result by two.
- For H₂: one.007 x 2 = 2.014 grams per mole; for O₂: xv.9994 x 2 = 31.9988 grams per mole; and for Cl₂: 35.453 x 2 = 70.096 grams per mole.
- Ane mnemonic device for remembering diatomic elements (molecules of 2 atoms) is: Accept No Fear Of Water ice Cold Beverages (Hydrogen, Nitrogen, Fluorine, Oxygen, Iodine, Chlorine, Bromine).^[5]

Find the chemical formula for the compound. This is the number of atoms in each chemical element that makes up the chemical compound. (This information is given in any chemistry reference book.) For example, the formula for hydrogen chloride (muriatic acid) is HCl; for glucose, it is C₆H₁₂O₆. Using this formula, you can identify the number of atoms of each element that makes upward the compound.
- For HCl, at that place is one atom of hydrogen and ane cantlet of chlorine.
- For C₆H₁₂O₆, there are half-dozen carbon atoms, 12 hydrogen atoms, and vi oxygen atoms.
2
Find the relative atomic mass of each element in the compound. Using the periodic tabular array, locate the relative diminutive mass for each element. Information technology is the number located beneath the symbol for the element.^[6] As we did in the get-go method of computing the tooth mass of an element, we volition likewise multiply these masses by i gram/mole.
- The relative atomic masses of the elements in muriatic acid are: hydrogen, 1.007 g/mol and chlorine, 35.453 k/mol.
- The relative atomic masses of the elements in glucose are: carbon, 12.0107 g/mol; hydrogen, 1.007 thousand/mol; and oxygen, xv.9994 thousand/mol.
three
Calculate the molar mass of each element in the chemical compound. Multiply the chemical element's atomic mass by the number of atoms of that element in the compound. This will give yous the relative amount that each chemical element contributes to the compound.^[7]
- For hydrogen chloride, HCl, the molar mass of each chemical element is 1.007 grams per mole for hydrogen and 35.453 grams per mole for chlorine.
- For glucose, C₆H₁₂O_six, the molar mass of each element is: carbon, 12.0107 x half dozen = 72.0642 g/mol; hydrogen, 1.007 ten 12 = 12.084 thousand/mol; and oxygen, 15.9994 x 6 = 95.9964 g/mol.
four
Add the tooth masses of each element in the chemical compound. This determines the molar mass for the entire chemical compound. Take the products y'all obtained in the previous footstep and add them all together to calculate the molar mass of the compound.
- For hydrogen chloride, the molar mass is i.007 + 35.453 = 36.460 g/mol. 36.46 grams is the mass of ane mole of hydrogen chloride.
- For glucose, the molar mass is 72.0642 + 12.084 + 95.9964 = 180.1446 1000/mol. 180.14 grams is the mass of one mole of glucose.

Article Summary X

When you're measuring extremely tiny amounts of a substance, it tin exist helpful to use tooth mass. According to the International Arrangement of Units, a mole is the amount of any substance that contains the aforementioned number of elementary entities—typically atoms or molecules—as in that location are atoms in 12 grams of the isotope carbon-12. Tooth mass is the mass in grams of i mole of whatsoever given substance. To find an element's molar mass, starting time by checking the periodic table for the relative atomic mass of the element. This is usually located under the symbol and name of the chemical element. For case, the relative diminutive mass of zirconium (Zr) is 91.22. Adjacent, multiply the atomic mass by the molar mass constant, which is equal to 1 gram per mole. For most elements, this ways that the relative atomic mass is equal to the tooth mass. For instance, zirconium has a molar mass of 91.22 10 1 k/mol, or 91.22 g/mol. All the same, some elements, such as hydrogen, nitrogen, and oxygen, only occur naturally in molecules of ii or more atoms. In these cases, you'll need to multiply the relative diminutive mass of the element by the number of atoms in the molecule, then multiply the result by the molar mass constant. For example, the molar mass of H2 is i.007 x ii x one g/mol, or 2.014 g/mol. Finding the molar mass of a chemical compound is a petty more complicated. First, you lot'll need to find the chemic formula for the compound. For example, if you're computing the molar mass of h2o, you'd start with the formula H2O. Then, calculate the molar mass of each element in the compound. Don't forget to take into account the number of atoms of each element when you make your calculation. In this example, the molar mass of the two hydrogen atoms is two.014 g/mol, while the single oxygen atom is 15.999 thou/mol. Add them together to get the total molar mass of eighteen.013 m/mol. To meet specific examples for how to calculate molar mass, read on!
