Answer

Explanation:

Step1: Identify the given and conversion factor

Given mass of CaO is 224.32 g, and 1 mole of CaO = 56.08 g.

Step2: Set up the calculation

We use the formula $n=\frac{m}{M}$, where $n$ is the number of moles, $m$ is the mass and $M$ is the molar - mass. Here, $n=\frac{224.32\ g}{56.08\ g/mol}$.

Step3: Calculate the number of moles

$n = \frac{224.32}{56.08}=4$ mol.

Answer:

4 moles of CaO
