Answer: -

5.376 x 10²³ atoms of nickel are in 52.4g of nickel.

Explanation: -

Mass of nickel = 52.4 g

Atomic mass of nickel = 58.69 g / mol

Number of moles of nickel = Mass of nickel / atomic mass

=
\frac{52.4 g{58.69 g / mol}

= 0.893 mol of Nickel.

According to Avogadro's Law,

1 mol of Nickel has 6.02 x 10²³ atoms of nickel.

0.893 mol of nickel has
(0.893 mol of nickel)/(1 mol of Nickel) x 6.02 x 10²³ atoms of Nickel

= 5.376 x 10²³ atoms of nickel.

5.376 x 10²³ atoms of nickel are in 52.4g of nickel.
