Question

A gaseous mixture contains He that exerts a pressure of 2 atm, Ne that exerts a pressure of

1.25 atm, and Ar that exerts a pressure of 1.5 atm. At constant temperature What is the
total pressure of the gas mixture?
4.75 atm
1.50 atm
Not enough information
3.00 atm

Answer 1

From Pressure total = Sum of partial pressure of all gases
Then P= partial pressure of He +partial pressure of Ne + partial pressure of Ar
P=2+1.25+1.5
=4.75
