Question

A Gaseous mixture contains 4.08g of oxygen and 2.78g of Nitrogen

a)What pressure is exerted by the mixture inside a 100.0ml metal container at 150C.

b) what pressure is contributed by the oxygen?

(please show steps)

Answer 1

Convert g O2 and g N2 to mols. mols = grams/molar mass

Then add mols and use PV = nRT to final total P. Remember T must be in kelvin.

To find P of individual gases, use n for that gas and PV = nRT.
