The moles of water are used in the given reaction between CO₂ & H₂O is 12 moles.
<h3>How do we calculate mass from moles?</h3>
Mass of any substance will be calculated by using their moles as:
n = W/M , where
W = given or required mass
M = molar mass
Given chemical reaction is:
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
Moles of 528 g of CO₂ = 528g / 44.01g/mol = 11.99 moles
From the stoichiometry of the reaction, it is clear that:
6 moles of CO₂ = reacts with 6 moles of H₂O
So, 11.99 moles of CO₂ = reacts with 11.99 = 12 moles of H₂O
Hence option (a)is correct i.e. 12 moles.
