How many liters of co2 are produced when 126 grams of glucose completely react with oxygen?

The complete combustion of glucose (C6H12O6) produces carbon dioxide (CO2) and water (H2O). The balanced chemical equation is: C6H12O6 + 6 O2 → 6 CO2 + 6 H2O. From this, we see that 1 mole of glucose produces 6 moles of CO2. Since the molar mass of glucose is approximately 180 g/mol, 126 grams of glucose corresponds to 0.7 moles. This will yield 0.7 moles × 6 moles CO2/mole glucose = 4.2 moles of CO2. At standard temperature and pressure (STP), 1 mole of gas occupies 22.4 liters, so 4.2 moles of CO2 will produce approximately 94.08 liters of CO2.
