A closed vessel contains equal numbers of

{O_2}

and

{H_2}

molecules at same

T

. Which of the following is not true?

View answer and explanation

Correct option: D

The weight of

{H_2}

is the same as the weight of oxygen

Option D (The weight of

{H_2}

is the same as the weight of oxygen) is correct because if the number of molecules is equal, the weights are not the same due to different molar masses.
