Question

Students at the University of North Texas and the Universityof Washington built a car propelled by compressed nitrogengas. The gas was obtained by boiling liquid nitrogen storedin a 200.0 L tank. What volume of N2 is releasedat 0.975 atm of pressure and 25 degrees C from a tank full ofliquid N2 (d = 0.808 g/mL)? ___ L Students at the University of North Texas and the Universityof Washington built a car propelled by compressed nitrogengas.

Explanation / Answer

We know P =dRT/M here temp is const in the process P(intial) =0.808*0.0821*298/28=0.706 PV= const V(final)=0.706*200/0.925=152.6L so volume released =47.4L
