Question

If a plant produces 9.31 mol of C6H12O6, how many moles of H2O are needed?

Answer 1

Ans. Ans. Balanced Reaction: 6CO₂ + 6H₂O ---hv---> C₆H₁₂O₆ + 6O₂

Stoichiometry: Formation of 1 mol glucose (C₆H₁₂O₆) requires 6 moles H₂O_.

So,

Total moles of H2O required = 6 x Number of moles of C₆H₁₂O₆ formed

                                                = 6 x 9.31 mol

                                                = 55.86 mol
