Determine the number of atoms of nickel (Ni) in a 5.05 grams solid nickel coin show your work pls
1 mol = 6.02 x 1023 atoms
1 mol = molar mass on ptable
Does anyone know the answer to this?

0.517× 10²³ atoms

Explanation:

Given data:

Mass of nickel = 5.05 g

Number of atoms of nickel = ?

Solution:

Formula:

Number of moles = mass/molar mass

Molar mass of nickel = 58.7 g/mol

by putting values,

Number of moles = 5.05 g/  58.7 g/mol

Number of moles =0.086 mol

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.  The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ atoms

0.086 mol  × 6.022 × 10²³ atoms / 1mol

0.517× 10²³ atoms
