Which of the following gases is the heaviest? o2, ch4, co2, cl2 o2 ch4 co2 cl2

Option (d) is the correct answer.

Explanation:

A molecule or compound which has large molecular mass will be the heaviest in nature.

Since we have to find the heaviest gas out of the given options, so we will calculate the molar mass of each gas as follows.

Molar mass of = 16 g/mol

Molar mass of = 16.04 g/mol

Molar mass of = 44.01 g/mol

Molar mass of = 70.90 g/mol

Thus, we can conclude that out of the given options is the heaviest gas.

i think its 5049.

i hope this !
