Answer the following showing all work.

1. A compound that is 40.0% C, 53.4% O, and 6.6% H. The molar mass of the compound is 120.grams. Find the EF and MF ?

2. Find the MF for the following: EF = CH₂O₁. Molar mass = 240.g/mole

3. Find the MF for the following: EF = Hg₁Cl₁. Molar mass = 472g/mole.

4. A compound that is 54.5% C, 31.8% N and 13.6% H. The molar mass of the compound is 88 grams. Find the EF and MF ?

Answers:1)MF = C₄H₈O₄ and EF = C₁H₂O₁, 2)MF = C₈H₁₆O₈, 3)MF = Hg₂Cl₂, 4)MF = C₄H₁₂N₂ and EF = C₂H₆N₁
