A gas mixture contains oxygen and argon at partial pressures of 0.60 atm and

425 mmhg. If nitrogen gas added to the sample increases the total pressure to 1250 torr, what is the partial pressure in Torr of the Nitrogen added?
Steps for solving this problem are greatly aprreciated!!!

PO2 = 0.6 atm x (760 mm/1 atm) = ?mm
PAr = 425 mm
Ptotal = 1250 mm
PN2 = 1250 - PO2 - PAr
nitrogen in torr
