If a plant produces 3.21 mol of c6h12o6, how many moles of co2 are needed?

Photosynthesis is the process by which CO₂ is converted to an organic compound. The complete reaction is as follows;
6CO₂ + 6H₂O --> C₆H₁₂O₆ + 6O₂
stoichiometry of CO₂ to C₆H₁₂O₆ is 6:1
For 1 mol of C₆H₁₂O₆ to be formed - 6 mol of CO₂ is required 
Therefore for 3.21 mol of C₆H₁₂O₆ to be formed - 6 x 3.21 mol of CO₂ required 
Number of moles required are - 19.26 mol of CO₂
