Question

Glucose, C6H12O6  is used as an energy source by the human body. The overall reaction in the body is described by the equation

C6H12+6O2-----> 6CO2+6H2O

Calculate the number of grams of oxygen required to convert 43.0g of glucose to CO2 and H2O

Answer 1

43.0 g glucose x 1 mol glucose / 180 g x 6 mols O₂ / mol glucose x 32 g O₂/mol = 45.9 g O₂
