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?

A. 0.228

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

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.
