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 moles

Use the formula $n=\frac{N}{N_A}$, where $N = 8.4\times 10^{24}$ atoms and $N_A=6.022\times 10^{23}$ atoms/mol. So $n=\frac{8.4\times 10^{24}}{6.022\times 10^{23}}$. $n=\frac{8.4}{6.022}\times10^{24 - 23}\approx1.4\times10^{1}=14$ mol.

Answer:

14 mol
