A mixture of He, Ne, and At has a pressure of 26.0 atm at 28.0 C, If the partial pressure of He is 3.02 atm and the partial pressure of At is 2.17 atm, what is the partial pressure of Ne?

Answer 1

The sum of the partial pressures must equal the total pressure.

Total pressure = 26.0 atm

26.0 atm = 3.02 atm + 2.17 atm + x atm

x atm = 26.0 - 3.02 - 2.17

x = 20.8 atm = partial pressure of Ne
