Find the oxidation of glucose to water and carbon dioxide

Question

1.     An important metabolic process of the body is the oxidation of glucose to water and carbon dioxide. The reaction is à C₆H₁₂O₆+ 60₂‑+6CO₂ + 6H₂0

a.   What mass of water in grams is produced when the body oxidizes 1.00 mol of glucose?

4.83 grams

b.  How many grams of oxygen are needed to oxidize 1.00 mol of glucose?

Answer 1

C₆H₁₂O₆ + 60₂ ==> 6CO₂ + 6H₂O ... balanced equation

a) 1.00 mol glucose x 6 mol H2O/mol glucose x 18 g H2O/mol H2O = 108 g H2O produced

b) 1.00 mol glucose x 6 mol O₂ / mol glucose x 32 g O₂/mol O₂ = 192 g O₂
