First off, Methane's chemical formula is CH4. So CH4 is the same as Methane.

Given:
32.08 g of CH4
16.04 g/mol of CH4

16.04 g/mol is basically 1 molecule of CH4 is 16.04 g.

Since you're trying to find out how much 32.08 g of CH4 is in molecules, you have to divide 32.08 g with 16.04 g/mol. 

The answer is 2 molecules. :)
