To find the number of atoms in 2.5 moles of magnesium, you can use Avogadro's number, which is approximately (6.022 \times 10^{23}) atoms per mole. Multiplying 2.5 moles by Avogadro's number gives you:
[
2.5 , \text{moles} \times 6.022 \times 10^{23} , \text{atoms/mole} \approx 1.51 \times 10^{24} , \text{atoms}.
]
Therefore, there are about (1.51 \times 10^{24}) atoms of magnesium in 2.5 moles.
