WebFind the number of moles of oxygen and nitrogen using PV=nRT which is n=PV/RT oxygen: ( (1 atm) (12L))/ (0.08206 atm L mol -1 K -1 ) (273 K)=0.536 moles oxygen nitrogen: ( (1 atm) (24.0L))/ (.08206 atm L mol -1 K -1 ) (273 K)=1.07 moles of Nitrogen add to get n tot: .536 mol Oxygen +1.07 mol Nitrogen =1.61 moles total Web28 apr. 2024 · Suppose the amount of OX2 in the gas mixture is n1 mol and the amount of NX2 in the gas mixture is n2 mol in volume of 1.0 L container. Thus, two parallel equations can be setup as follows: PV = nRT ⇒ n1 + n2 = PV RT = 4 × 1 0.082 × 298 = 0.164 32n1 + 28n2 1 = 4.7 ⇒ 32n1 + 28n2 = 4.7
