the chemical equation below shows the photosynthesis reaction. 6co2 + 6h2o → 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

Explanation:

Step1: Calculate moles of CO₂

Use formula $n=\frac{m}{M}$, where $n$ is moles, $m$ is mass and $M$ is molar - mass. Given $m = 528g$ and $M = 44.01g/mol$. $n_{CO_2}=\frac{528g}{44.01g/mol}\approx12mol$

Step2: Use mole - ratio from chemical equation

The balanced chemical equation is $6CO_2 + 6H_2O\rightarrow C_6H_{12}O_6+6O_2$. The mole - ratio of $CO_2$ to $H_2O$ is $6:6 = 1:1$. So, $n_{H_2O}=n_{CO_2}$ Since $n_{CO_2}\approx12mol$, then $n_{H_2O}=12mol$

Answer:

12.0 moles
