Question

The chemical equation below shows the photosynthesis reaction. 6co2 6h2o right arrow. c6h12o6 6o2 the molar mass of carbon dioxide (co2) is 44.01 g/mol. the molar mass of water (h2o) is 18.02 g/mol. a reaction uses 528 g of co2. how many moles of water are used in this reaction? 12.0 moles 72.0 moles 216 moles 528 moles

Answer 1

The moles of water are used in the given reaction between CO₂ & H₂O is 12 moles.

How do we calculate mass from moles?

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.
