Question

Plants convert carbon dioxide and water to glucose (C6H12O6) and oxygen in the process of photosynthesis. Write a balanced equation for this reaction, and determine how many moles of CO2 are required to produce 15.0 mol of glucose.

Answer 1

$6CO_2+6H_2O+ (energy)\to C_6H_{12}O_6+6O_2$

Mole ratio, $CO_2:C_6H_{12}O_6=6:1$

Moles of $CO_2$ required $=6\times 15=90 moles$
