Education & Reference - 28 November 2006

I only have two questions left and I can't get them....will someone please help?

1. If 4.04g of Na combine with 11.46g of O to produce a compound with a formula mass of 108.0 amu, what is the molecular formula of this compound?

2. A compound containing sodium, chlorine, and oxygen is 25.42% sodium by mass. A 3.25g sample gives 4.33*10^22 atoms of oxygen. What is the empirical formula?

** If you need the atomic masses for these problems, they are :
Na-23 ; O-16 ; Cl-35.45

Thank you for any help.
