Ethanol, used in alcoholic beverages, can be produced by fermentation of sucrose. The balanced equation for the fermentation process is shown below. What mass of ethanol (C2H5OH) would be produced when 2.61 g sucrose reacts by this process?

Question

C12H22O11(s) + H2O(l) → 4 C2H5OH(l) + 4 CO2(g)

Answer 1

4C12H22O11(s) + H2O(l) → 4 C2H5OH(l) + 4 CO2(g)
mols sucrose = grams/molar mass = 2.61/342 = ?
Then convert mols sucrose to mols alcohol produced. That is
?mols sucrose x (4 mols C2H5OH/4 mols C12H22O11) = ?
gram ethanol = mols ethanol x molar mass ethanol = ?
