A20-l flask contains a mixture of nitrogen gas and oxygen gas at 25 °c.
the total pressure of the gaseous mixture is 0.91 atm, and the mixture is
own to contain 0.050 mol n2. calculate the partial pressure of oxygen
and the moles of oxygen present.

At a temperature of 393 k, the temperature of a sample of nitrogen is 1.07 atm what will the pressure be at a temperature of 478 k
