Answer

Explanation:

Step1: Recall Avogadro's number

Avogadro's number ($N_A$) is $6.022\times 10^{23}$ atoms/mol.

Step2: Calculate the number of atoms

The number of atoms $N$ in $n$ moles is given by $N = n\times N_A$. Here, $n = 2$ moles. So $N=2\ mol\times6.022\times 10^{23}\ atoms/mol$. $N = 2\times6.022\times 10^{23}\ atoms\approx1.2044\times 10^{24}\approx1\times 10^{24}$ atoms.

Answer:

$1\times10^{24}$ Al atoms
