The chemical equation shows the photosynthesis reaction. 6 CO sub 2 plus 6 cap h sub 2 cap o rightarrow cap c sub 6 cap h sub 12 cap o sub 6 plus 6 cap o sub 2 The molar mass of carbon dioxide open paren CO sub 2 close paren is 44 point 0 1 g over mol The molar mass of water open paren cap h sub 2 cap o close paren is 18 point 0 2 g over mol A reaction uses 528 g of CO sub 2 How many moles of water are used in this reaction?
Convert the carbon dioxide mass to moles: 528 g ÷ 44.01 g/mol ≈ 12.0 mol CO₂. The balanced equation uses 6 mol H₂O for every 6 mol CO₂, so the mole ratio is 1:1. Therefore, 12.0 mol of water are used, which is choice D.
