Can someone help me with empirical formula and molar mass?

How do I find out the empirical formula of a molecule and how do I find the molecular formula?
 
Ex:
   1. What's the empirical formula of a molecule containing 65.5% carbon, 5.5% hydrogen, and 29.0% oxygen?
   2. If the molar mass of the compound in problem 1 is 110 grams/mole, what’s the molecular formula?
