$1.5 \times 10^{24}$ $1.5 xx 10^24$ molecules.

Explanation:

You can calculate the number of molecules from moles by using Avogadro's constant, $6.02 \times 10^{23}$ $6.02 xx 10^23$ $molecules/mol$ $"molecules/mol"$ .

For every $1$ $1$ mol, there are $6.02 \times 10^{23}$ $6.02 xx 10^23$ molecules.

Simply multiply

$2.5 mol \times \frac{6.02 \times 10^{23}}{1 mol} = 1.5 \times 10^{24}$ $"2.5 mol" xx (6.02 xx 10^23)/"1 mol" = 1.5 xx 10^24$ $molecules$ $"molecules"$
