Question

Green plants use light from the sun to drive photosynthesis, a chemical reaction in which liquid water and carbon dioxide gas form aqueous glucose (C₆H₁₂O₆) and oxygen (O₂) gas. Calculate the moles of water needed to produce 0.10 mol of glucose. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits.

Answer 1

0.60 mol of water is needed to produce 0.10 mol of glucose.

Step-by-step explanation:

In the chemical equation for photosynthesis, 6 moles of water (H2O) are needed to produce 1 mole of glucose (C6H12O6). Therefore, to calculate the moles of water needed to produce 0.10 mol of glucose:

1. Set up the proportion: (0.10 mol glucose)/(1 mol glucose) = (x mol water)/(6 mol water)
2. Cross-multiply and solve for x:

x = (0.10 mol glucose × 6 mol water) / 1 mol glucose = 0.60 mol water

Therefore, 0.60 mol of water is needed to produce 0.10 mol of glucose.
