發問:
find the density of nitrogen dioxide at 0.97 atm and 35 oC
最佳解答:
Pressure, P = 0.97 atm Molar mass, M = 14 + 16x2 = 46 g mol?1 density, d = ? Gas constant, R = 0.082 atm L mol?1 K?1 Absolute temperature, T = 273 + 35 = 308 K PV = nRT PV = (m/M)RT PM = (m/V)RT PM = dRT d = PM/(RT) Density, d = 0.97 x 46 / (0.082 x 308) = 1.77 g L?1
