Question

The reaction for producing glucose in plants, called photosynthesis, is:

6CO2 + 6H2O light ------> C6H12O6 + 6O2.
1. If a plant produces 6.86 mol C6H12O6 , how many moles of H2O are needed?

Answer 1

41.16 moles of H2O

Step-by-step explanation:

Ratio for the products-reactants is 1:6, so 1 mol of glucose is produced when plants use 6 moles of water.

Then, let's make a rule of three:

1 mol of glucose is produce by using 6 moles of water

6.86 moles of glucose are produced by the use of (6 . 6.86)/1 = 41.16 moles of H2O
