Answer

Answer:

3.20 mol

Explanation:

Step1: Identify the conversion factor

We know that 1 mol of $\ce{KNO3}$ has a mass of 101.11 g.

Step2: Set up the calculation

The number of moles $n$ of $\ce{KNO3}$ is calculated by the formula $n=\frac{m}{M}$, where $m = 324$ g is the mass and $M=101.11$ g/mol is the molar - mass. So $n=\frac{324\ g}{101.11\ g/mol}$.

Step3: Calculate the result

$n=\frac{324}{101.11}\approx3.2044$ mol.

Step4: Round the answer

Rounding 3.2044 mol to two decimal places gives 3.20 mol.
