Glucose reacts with oxygen to form carbon dioxide and water
according to the following unbalanced reaction: C6H12O6 (s,
glucose) + O2 (g) → CO2 (g) + H2O (g) If we start with 25.5 g of
glucose and 37.3 g of oxygen, how many grams of the excess reactant
are leftover after the reaction is complete? Report your answer to
THREE significant figures.
