What mass, in grams, of glucose is produced when 3.00mol of water react with carbon dioxide?

In photosynthesis, plants use energy from the sun to produce glucose, C6H12O6, and oxygen from the reaction of carbon dioxide and water. What mass, in grams, of glucose is produced when 3.00 mol of water react with carbon dioxide?

6 CO2 + 6 H2O -> C6H12O6 + 3 O2

Molar mass of water = 18g/mol
Molar mass of glucose = 180g/mol

3mol of water will produce 0.5 mol of glucose.

Mass in grams = molar mass * moles

0.5*180=90 grams of glucose.
