The number of gram molecules of oxygen in 6.02 x 10²⁴ CO molecules is
Options
(a) 10 gm molecules
(b) 5 gm molecules
(c) 1 gm molecules
(d) 0.5 gm molecules
Correct Answer:
5 gm molecules
Explanation:
6.02 x 10²³ molecules of CO = 1 mole of CO
6.02 x 10²⁴ molecules of CO = 10 mole of CO
= 10 g atoms of O = 5 g molecules of O₂
