Question

Determine the pressure of oxygen at 0°c if the density of oxygen at ntp=1.44kg/m³ and rms speed of molecules at ntp=456.3m/s

Answer 1

Given: Density = ρ = 1.44 kg/m3, condition N.T.P., P = 76 cm of Hg = 0.76 x 13600 x 9.8 = 1.013 x 105 N/m2, r.m.s. speed = C = 456.4 m/s

To Find: Pressure of gas = P = ?

Ans: Pressure of oxygen = 105 N/m2
