The number of oxygen atoms in 4.4g of CO₂ is

Options

(a) 1.2 x 10²³
(b) 6 x 10²²
(c) 6 x 10²³
(d) 12 x 10²³

Correct Answer:

1.2 x 10²³

Explanation:

Atomic Mass of C=12
Atomic Mass of O=16
mol.wt of CO₂=12 + (16 x 2) = 44
4.4 g CO₂ = 4.4/44 = 0.1 mol CO₂
=6.02 x 10²² molecules
=2 x 6 x 10²² atoms of O
