Sulfur trioxide dissolves in water to make sulfuric acid, H2SO4. a. Write a balanced chemical equation for the reaction.

b. Calculate the mass of sulfuric acid that could be produced from the reaction of 10.0 mL of water (d=1.00g/mL) and 20.0 g of SO3?

c. Yeast converts glucose (C6H12O6) into ethanol (d=0.789g/mL) in a process called fermentation. An equation for the reaction can be written as follows:
___C_6 H_12 O_(6(aq) ) → C_2 H_5 OH_((l) )+ CO_(2(g))

i. Balance the equation.

ii. If the percent yield of ethanol is only 77.1%, how many grams of glucose must react to make 80.0mL of ethanol?
