Consider again the reaction for photosynthesis:
sveticcg [70]

Mass of water required = 64.42 g

<h3>Further explanation</h3>

Given

Reaction

6CO2 + 6H2O → C6H12O6 + 6O2

157.35 g CO2

Required

mass of water

Solution

mol CO₂ = mass : MW CO₂

mol CO₂ = 157.35 g : 44.01 g/mol

mol CO₂ = 3.575

From the equation, mol ratio CO₂ : H₂O = 6 : 6, so mol H₂O = mol CO₂=3.575

Mass H₂O = mol x MW H₂O

mass H₂O = 3.575 x 18.02

mass H₂O = 64.42 g
