An apparatus consists of a 4 L flask containing nitrogen gas at 32C and 885 kPa, joined by a valve to a 8 L flask containing argon gas at 32 C and 47.5 kPa. The valve is opened and
the gases mix. What is the partial pressure of nitrogen after mixing?
Answer in units of kPa

Effectively all you are doing is letting the N2 gas in the 4L container expand to a total of 12 L so the pressure of the N2 gas will be
885 x 4/12 = ? kPa.
