A gaseous mixture in a 25.00 L container is made of 16.0 g N2 and 14.0 g Ar and
has a total pressure of 1.00 atm.
1.Calculate the partial pressure of the N2 in the mixture. the ans is 0.620 atm
2.Calculate the temperature of the gas mixture.
can someone explain to me how to do the second part please?

Dr Russ,
use PV=nRT where n is the total number of moles.
Use V=25.00 L
P =1.00 atm
you needed to calculate n for the first part.
Make sure that use the correct value for R based on the units.
