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

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
