How to calculate moler mass

To calculate the molar mass of a compound, follow these steps:

1. Determine the chemical formula of the compound.
2. Look up the atomic masses of each element in the compound from the periodic table.
3. Multiply the atomic mass of each element by the number of atoms of that element in the compound.
4. Add up the total atomic masses of all the elements in the compound to get the molar mass.

For example, let's calculate the molar mass of water (H2O):
- The atomic mass of hydrogen (H) is 1.008 g/mol and the atomic mass of oxygen (O) is 16.00 g/mol.
- In water, there are 2 atoms of hydrogen and 1 atom of oxygen.
- Calculate the molar mass: (2 x 1.008 g/mol) + (1 x 16.00 g/mol) = 18.02 g/mol

Therefore, the molar mass of water is 18.02 g/mol.
