Mass of one atom of X is 2.66 x 10⁻²³ g, then its 32 g is equal to

Options

(a) 32 x 2.66 x 10⁻²³ mol
(b) 32 / (2.66 x 10⁻²³ x 6.023 x 10²³) mol
(c) (32 x 2.66 x 10⁻²³) / (6.023 x 10²³) mol
(d) none of the above

Correct Answer:

32 / (2.66 x 10⁻²³ x 6.023 x 10²³) mol

Explanation:

Mass of one atom = 2.66 x 10⁻²³
Atomic Mass =2.66 x 10⁻²³ x 6.02 x 10²³ g mol⁻¹
No. Moles in 32 g = 32 / Atomic Mass
