We tend to think the greater the mass, the greater the volume but that is not true. What weighs more a pound of lead or a pound of feathers? Obviously they are the same however there would be a lot more feathers than lead. Mass and volume are not really related.
The mass of a nickel coin is 5 g.
1 mol of Ni weighs 58 g. 1 mol contains 6.022 x 10²³ atoms of Ni.
therefore in 58 g there are 6.022 x 10²³ atoms of Ni
then in 5 g the number of Ni atoms are - 6.022 x 10²³ /58 x 5 = 5.2 x 10²² Ni atoms
Therefore number of Ni atoms are 5.2 x 10²² atoms in a nickel coin
