How many atoms are in 0.534 mol of nickel, Ni?

Question

Quizplus · Accepted Answer

To calculate the number of atoms in a given amount of substance (in this case, 0.534 mol of Ni), we first need to use Avogadro's number to convert from moles to atoms.

Avogadro's number is defined as the number of atoms, molecules, or ions in one mole of a substance, which is approximately 6.022 × 10²³. Therefore:

0.534 mol Ni × (6.022 × 10²³ atoms/mol) = 3.22 × 10²³ atoms Ni

Therefore, the answer is D, 3.22 × 10²³ atoms.
