Answer

Explanation:

Step1: Calculate moles of CO₂

Use the formula $n=\frac{m}{M}$, where $n$ is moles, $m$ is mass, and $M$ is molar - mass. Given $m = 528\ g$ and $M_{CO_2}=44.01\ g/mol$. So, $n_{CO_2}=\frac{528\ g}{44.01\ g/mol}\approx12\ mol$.

Step2: Use mole - ratio from the balanced equation

The balanced equation $6CO_2 + 6H_2O\rightarrow C_6H_{12}O_6+6O_2$ shows that the mole - ratio of $CO_2$ to $H_2O$ is $1:1$ ($\frac{n_{H_2O}}{n_{CO_2}}=\frac{6}{6} = 1$). So, $n_{H_2O}=n_{CO_2}$. Since $n_{CO_2}\approx12\ mol$, then $n_{H_2O}=12\ mol$.

Answer:

12.0 moles
