question 1 (2 points)\nhow many atoms of c are in 0.522 moles c?\n6.02 x 10^23\n3.14 x 10^23\n8.67 x…

Explanation:

Step1: Recall Avogadro's number

Avogadro's number ($N_A$) is $6.02\times 10^{23}$ atoms/mol.

Step2: Calculate the number of atoms

The number of atoms $N$ of a substance is given by $N = n\times N_A$, where $n$ is the number of moles. Here, $n = 0.522$ mol and $N_A=6.02\times 10^{23}$ atoms/mol. So $N=0.522\times6.02\times 10^{23}$. $N = 3.14244\times 10^{23}\approx3.14\times 10^{23}$ atoms.

Answer:

$3.14\times 10^{23}$ (corresponding to the second option)
