QuestionFind the moles of $\mathrm{Cl}$ in $3.01 \times 10^{24}$ units of $\mathrm{MgCl}_{2}$. Give your answer in moles.

Studdy Solution
Calculate the number of moles of chlorine atoms.
$$\text{Number of moles of Cl} = \frac{6.02 \times10^{24}}{6.022 \times10^{23}} =10 \text{ moles}$$There are10 moles of chlorine atoms in $3.01 \times10^{24}$ formula units of magnesium chloride, $\mathrm{MgCl}_{2}$.
