To calculate the molar mass of a compound in chemistry, you need to know the atomic mass of each element present in the compound and the number of atoms of each element in the molecule. First, find the atomic mass of each element by consulting the periodic table of elements. Next, multiply the atomic mass of each element by the number of atoms of that element in the compound. Then, add the products of these multiplications together to find the molar mass of the compound.

For example, the molar mass of water (H2O) can be calculated by adding the atomic masses of two hydrogen atoms and one oxygen atom: (2 x 1.008 g/mol) + (1 x 15.999 g/mol) = 18.015 g/mol. Therefore, the molar mass of water is 18.015 grams per mole (g/mol).

The molar mass of a compound is the mass of one mole of that compound. It is calculated by multiplying the atomic mass of each element in the compound by its subscript in the chemical formula, and then adding all of the products together. For example, the molar mass of water (H2O) is 18.015 grams per mole, because the atomic mass of hydrogen is 1.00794 grams per mole and the atomic mass of oxygen is 15.9994 grams per mole, and there are two hydrogen atoms and one oxygen atom in each molecule of water.

Here are the steps on how to calculate the molar mass of a compound:

  1. Write down the chemical formula of the compound.
  2. Look up the atomic mass of each element in the periodic table.
  3. Multiply the atomic mass of each element by its subscript in the chemical formula.
  4. Add all of the products together.
  5. The answer is the molar mass of the compound.

Here are some examples of how to calculate the molar mass of a compound:

  • The molar mass of water (H2O) is 18.015 grams per mole.
  • The molar mass of carbon dioxide (CO2) is 44.01 grams per mole.
  • The molar mass of sodium chloride (NaCl) is 58.44 grams per mole.
  • The molar mass of glucose (C6H12O6) is 180.16 grams per mole.
