Cl₂
Explanation:
The gas with the highest molecular mass will be considered the heaviest of all of them.
To solve this problem, we must calculate the molecular mass of the given gases;
O₂ CH₄ CO₂ and Cl₂
O₂ molecular mass = 15.9998 x 2 = 32g/mol
CH₄ = 12 + 4(1) = 16g/mol
CO₂ = 12 + 2(16) = 44g/mol
Cl₂ = 2(35.5) = 71g/mol
The heaviest of the gases given is Cl₂ because it has the highest molar mass compared to other gases.
