Answer: 0.0450 moles of CaCl_2

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to its molecular mass and contains avogadro's number 6.023\times 10^{23} of particles.

To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}

\text{Number of moles of} CaCl_2=\frac{5.00g}{110.98g/mol}=0.0450moles

Thus there are 0.0450 moles of CaCl_2
