What is the mass (g) of 7.32x10^15 atoms of (Sn)

144.7×10^-8g of tin

Explanation:

Recall from Avogadro's law that the number of elementary entities (atoms, molecules, ions etc) in one mole of a substance is equal to the Avogadro's number which has a numerical equivalent of 6.02×10^23.

1 mole of tin has a mass of 119g

Hence 119g of tin has 6.02 ×10^23 atoms of tin

x g of tin will have 7.32x10^15 atoms of tin

x= 7.32x10^15 × 119/ 6.02 ×10^23

x= 144.7×10^-8g of tin
