1. The problem statement, all variables and given/known data 4.60×1023 nitrogen molecules collide with a 20.0cm^2 wall each second. Assume that the molecules all travel with a speed of 450m/s and strike the wall head on. What is the pressure on the wall in pascals (Pa)? 2. Relevant equations p=(1/3)*(N/V)*(m*v_rms^2) where, N is the number of molecules: 4.60*10^23 V is the volume: 0.002m^2 m is the mass (diatomic): (14u*2*1.66*10^-27kg/u) v is the rms speed 450m/s? 3. The attempt at a solution p=(1/3)*(4.60*10^23/0.002)*(450^2)*(14*2*1.66*10^-27)=722*10^3Pa Am I wrong on the v_rms? The v_rms is almost always within 10% of the v_avg.
