The density of solid ag is 10.5 g/cm3. how many atoms are present per cubic centimeter of ag?

The molar mass of Ag is 108 grams per mole.

So, divide the density of Ag which is 10.5 g/cm3 by 108 grams per mole and you will get 0.0972 moles per cubic centimeter.

Using Avogadro’s law where 1 mole of substance equals 6.023 x 10^23 atoms

0.0972 moles per cubic centimeter (6.023 x 10^23 atoms/mole) = 5.86 x 10^22 atoms Ag

thats how its supposed to be
