Green plants use light from the Sun to drive photosynthesis. Photosynthesis is a chemical reaction in which water H2O and carbon dioxide CO2 chemically react to form the simple sugar glucose C6H12O6 and oxygen gas O2. What mass of water is consumed by the reaction of 6.49g of carbon dioxide?

ANSWER:

2.65 g H2O

Explanation:

6.49g (co2) / 44.009g (co2)  x  1 mol (co2) / 1 mol (h2o)  x 1 mol (h2o)    

=0.147 mol H2O

0.147 mol (H2O) / 1 mol (h2o) x 18.015 g (h2o)

=2.65 g H2O
