Which one of the following will have largest number of atoms?(i) 1 g A

1.	Which one of the following will have largest number of atoms?(i) 1 g Au (s)(ii) 1 g Na (s)(iii) 1 g Li (s)(iv) 1 g of Cl2 (g)
Answer» (i) Number of atoms in 1 g of Au = {197}/{6.022 x 10²³} = 32.7 x 10^-23 (ii) Number of atoms in 1 g Na = {2.3}/{6.022 x 10²³} = 3.82 x 10^-23 (iii) Number of atoms in 1 g of Li = {7}/{6.022 x 10²³} = 1.16 x 10^-23 (iv) Number of atoms in 1 g Cl₂ = {35.5}/{6.022 x 10²³} = 5.89 x 10^-23 1 g gold will have the largest number of atoms.

Which one of the following will have largest number of atoms?(i) 1 g Au (s)(ii) 1 g Na (s)(iii) 1 g Li (s)(iv) 1 g of Cl2 (g)

Answer»

(i) Number of atoms in 1 g of Au = {197}/{6.022 x 10²³} = 32.7 x 10^-23

(ii) Number of atoms in 1 g Na = {2.3}/{6.022 x 10²³} = 3.82 x 10^-23

(iii) Number of atoms in 1 g of Li = {7}/{6.022 x 10²³} = 1.16 x 10^-23

(iv) Number of atoms in 1 g Cl₂ = {35.5}/{6.022 x 10²³} = 5.89 x 10^-23

1 g gold will have the largest number of atoms.
