Question

how many atoms are in 6.3 mol zn? 3.8x10^24 atoms zn 410 atoms zn 1.0x10^-23 atoms zn 6.0x10^23 atoms zn

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 a given number of moles $n$ is given by $N = n\times N_A$. Here, $n = 6.3$ mol. So $N=6.3\times6.022\times 10^{23}$.
$N = 37.9386\times 10^{23}\approx3.8\times 10^{24}$ atoms.

Answer:

3.8×10²⁴ atoms Zn
