1. Fructose, a sugar found in fruit, contains only carbon, oxygen, and hydrogen. It is used in ice cream to prevent a sandy texture. Complete combustion of 32.4 mg of fructose in oxygen produced 47.6 mg of CO2and 19.4 mg of H2O. What is the empirical formula of fructose?

2. If 6.35 g of copper gives 2.4 g of sulfur dioxide via the following reaction, determine the percent yield of sulfur dioxide. Assume sulfuric acid is present in excess.

Cu(s) +H2SO4(aq)----> CuSO4(aq) +SO2(g) + H2O
