Using a chemical equation to find moles of product from moles of reactant. 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 C₆H₁₂O₆ O₂ gas. Calculate the moles of glucose produced by the reaction of 1.9 mol of water. Be sure your answer has a unit symbol, if necessary, and round it to 2 significant digits.
