57.7 g Ni contains how many atoms? A) 6.13 × 10²³ atoms B) 3.47 × 10²³ atoms C) 5.92 × 10²³ atoms D) 1.24 × 10²⁴ atoms E) 0.983 atoms

Question

Quizplus · Accepted Answer

To calculate the number of atoms in 57.7 g of nickel, we first need to convert grams to moles using the molar mass of nickel:

57.7 g Ni × (1 mol Ni / 58.69 g Ni) = 0.982 mol Ni

Next, we can use Avogadro's number (6.022 × 10^23 atoms/mol) to convert moles to atoms:

0.982 mol Ni × (6.022 × 10^23 atoms/mol) = 5.92 × 10^23 atoms

Therefore, the answer is (C) 5.92 × 10^23 atoms.
