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

Question

Quizplus · Accepted Answer

To find the number of atoms in 57.7 g of Ni, we need to use the Avogadro's number and the atomic mass of Ni.

Atomic mass of Ni = 58.69 g/mol

Number of moles of Ni = 57.7 g / 58.69 g/mol = 0.9822 mol

Number of atoms of Ni = 0.9822 mol x 6.022 x 10^23 atoms/mol = 5.92 x 10^23 atoms

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