Question

The number of atoms present in 4.8g of carbon-12

Answer 1

answer of above question is following

Answer 2

The molar mass of Carbon 12 is :

12 g

Moles of Carbon 12 in 4.8 g is :

4.8/12 = 0.4 moles

According to Avogadros constant :

1 mole —> 6.022 × 10^23 atoms

The number of atoms in 0.4 moles is :

0.4 × 6.022 × 10^23 = 2.4088 × 10^23 atoms
