Homework Help: Chemistry

Last one I promise! Thankyou for bearing with me. This seems simple enough, but chemistry genuinely makes me feel retarded so I appreciate reassurance.

How many molecules of CH4 are there in 48.2g of the compound?

I'm assuming that I should just divide 48.2 g by the molar mass of CH4 which is 16.05g, and it calculates to 3 mols. Is this correct?
