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. 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

Explanation / Answer

PV = nRT V = [((200 L * 0.000808 g/ L)*(1 mol N2 / 28 g N2))*(8.3145J/mol K)*(273 + 25))] / (0.975 atm) = 14.667 L
