Question

According to the following reaction, how many moles of oxygen gas are necessary to form 0.318 moles carbon dioxide?

1 mol glucose + 6 mol O2 --> 6 mol CO2 + 6 mol H2O

Answer 1

From the reaction,

1 mol glucose + 6 mol O₂ --> 6 mol CO₂ + 6 mol H₂O

It is clear that 1.0 mole of O₂ required to produce 1.0 mole of CO₂ .

Thus, no. of moles of  O₂ = no. of moles of CO₂ = 0.318 moles (Ans)

0.318 moles of oxygen gas are necessary to form 0.318 moles carbon dioxide.
