Which of the following gases is the least soluble in water and why? CO2, SO3, N2, NH3, HCl.
Fofino [41]

Answer:

SO3

It has the highest molar mass value and thus would be the least soluble

Explanation:

In this question, we want to know which of the gases is the least soluble in water.

The easiest way to do this is to calculate the molar masses of these gases. The gas with the highest molar mass is the heaviest and thus will be the least soluble in water

For CO2 - molar mass is 44 g/mol

For SO3- molar mass is 80 g/mol

For N2- molar mass is 28g/mol

For NH3-molar mass is 17g/mol

For HCl- molar mass is 36.5 g/mol

From the molar masses, we can see that the molar mass of the ammonia gas is the lightest and thus, it is the most soluble.

The mass of the sulphur vi oxide is the highest and thus it is the heaviest and the least soluble in water
