Answer

Answer:

13.8

Explanation:

Step1: Identify mole - ratio

From the reaction $2KMnO_4 + 16HCl\rightarrow2KCl + 2MnCl_2+8H_2O + 5Cl_2$, the mole - ratio of $KMnO_4$ to $H_2O$ is $\frac{n_{H_2O}}{n_{KMnO_4}}=\frac{8}{2}=4$.

Step2: Calculate moles of $H_2O$

Given $n_{KMnO_4}=3.45$ moles. Using the mole - ratio, $n_{H_2O}=4\times n_{KMnO_4}$. So $n_{H_2O}=4\times3.45 = 13.8$ moles.
