The balanced chemical reaction is:

C4H8O2 + 2H2--> 2C2H6O

A. How many grams of ethyl alcohol are produced by reaction of 2.7 mol of ethyl acetate with H2? 2.7 mol C4H8O2 (2 mol C2H6O / 1 mol C4H8O2) (46.07 g / 1 mol) = 248.78 g ethyl alcohol

B. How many grams of ethyl alcohol are produced by reaction of 13.0g of ethyl acetate with H2?

13.0 g C4H8O2 (1 mol / 88.11 g) (2 mol C2H6O / 1 mol C4H8O2) (46.07 g / 1 mol) = 13.59 g ethyl alcohol

C. How many grams of H2 are needed to react with 13.0g of ethyl acetate?

13.0 g C4H8O2 (1 mol / 88.11 g) (2 mol H2 / 1 mol C4H8O2) (2.02 g / 1 mol) = 0.5961 g H2
