Expert Answer

Step 1

According Dalton’s law, the total pressure exerted  by  a mixture of gases is the total sum of the partial pressure of the individual gases present in the mixture.  The mathematical expression is:

Step 2

Given:

Total pressure of the gas mixture = 16.7 atm 

Partial pressure of He =2.02 atm 

Partial pressure of...
