Question

hurry please! a mixture of He, Ne, and N2 gases has a pressure of 1.348 atm. if the pressures of He and Ne are 0.124 atm and 0.996 atm, respectively, what is the partial pressure of N2 in the mixture?

Answer 1

A. 0.228

Step-by-step explanation:

Partial pressure as name suggests is partial pressures that add up to a final (total) pressure.

Here total pressure is 1.348 atm.

He + Ne + N2 = 1.348

0. 124 + 0.996 + N2 = 1.348

N2 = 0.228
