1. Identify the elements and their atomic masses:

* Carbon (C): 12.0 amu

* Hydrogen (H): 1.0 amu

2. Determine the number of atoms of each element in the molecule:

* Methane (CH4) has 1 carbon atom and 4 hydrogen atoms.

3. Calculate the total mass of the molecule:

* (1 carbon atom * 12.0 amu/carbon atom) + (4 hydrogen atoms * 1.0 amu/hydrogen atom) = 16.0 amu

4. Convert amu to grams per mole (g/mol):

* 1 amu = 1 g/mol

Therefore, the molar mass of methane (CH4) is 16.0 g/mol.
