Answer 1

Answer on Question #59922 – Chemistry– Other

**Question:**

How many moles of magnesium are in $3.01 \times 10^{22}$ atoms of magnesium?

**Answer:**

$$n = N / N_{A}$$

where $n$ is amount of moles of magnesium, $N$ is number of atoms of magnesium, $N_{A}$ is a Avogadro constant, which is $6.02 \times 10^{23} \, \text{mol}^{-1}$

So $n = 3.01 \times 10^{22} / 6.02 \times 10^{23} = 0.05 \, \text{mol}$
