1 mole of Ne weighs 20 g and has 6.023 × 1023 atoms
60 g of Ne will have = 6.023×10^{23}\over 20 × 60
= 60\over 20 × 6.023 × 1023
= 3 × 6.023 × 1023
Hence, number of atoms in 60 g of Ne = 3 × 6.023 × 1023 atoms
1 mole of Ne weighs 20 g and has 6.023 × 1023 atoms
60 g of Ne will have = 6.023×10^{23}\over 20 × 60
= 60\over 20 × 6.023 × 1023
= 3 × 6.023 × 1023
Hence, number of atoms in 60 g of Ne = 3 × 6.023 × 1023 atoms
