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

12 moles of water (H₂O)

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

6CO₂ + 6H₂O —> C₆H₁₂O₆ + 6O₂

From the balanced equation above,

6 moles of H₂O reacted to produce 1 mole of C₆H₁₂O₆.

Finally, we shall determine the number of mole of H₂O required to produce 2 moles of C₆H₁₂O₆. This can be obtained as follow:

From the balanced equation above,

6 moles of H₂O reacted to produce 1 mole of C₆H₁₂O₆.

Therefore, Xmol of H₂O will react to produce 2 moles of C₆H₁₂O₆ i.e

Xmol of H₂O = 6 × 2

Xmol of H₂O = 12 moles.

Thus, 12 moles of water (H₂O) is needed to produce 2 moles of glucose (C₆H₁₂O₆).
