Question

Sugar reacts with oxygen as : 

C₁₂H₂₂ O_H + 12O₂ ----> 12CO₂ + 11H_2O. How many g of CO₂ is produced per g of sucrose (sugar) used. How many mole of oxygen are needed to react with 1.0 g sugar. 

Answer 1

1 mole or 342 g sugar produces 12 mole or 44 x 12 g CO₂  

1 g sugar produces 44 x 12/ 342 = 1.54 g CO₂

Also 1 mole or 342 g sugar requires 12 mole O₂

1 g sugar requires 12/342 = mole O₂ = 3.5 x 10^-2 mole
