Question

A colorless liquid composed of 456.68% nitrogen and 53.32% oxygen has a molar mass of 60.01g/mol. What is the molecular formula for this compound?

Answer 1

Since each O brings 16 g/mol, and each N brings 14 g/mol., what combinations of 16s and 14s gives 60?

That's the guess and check method. The better method is calculating the empirical formula.
