In a period of 1.3 s, 5.0  1023 nitrogen molecules strike a wall of area 7.6 cm2. If the molecules move at 320 m/s and strike the wall head on in a perfectly elastic collision, find the pressure exerted on the wall. (The mass of one N2 molecule is 4.68  10-26 kg.)

the difference of rhe speed when molecules strikes a wall : 
∆v = 320 - (-320) = 640 m/s 

The force exerted on the wall : 
F =n * ∆p/∆t = n * m∆v/∆t = 5.0 × 10^23 * 4.68 × 10^–26 * 640/1.3 = 11.52 N 

The pressure exerted on the wall : 
p = F/A = 11.52 / 7.6 x 10^-4 = 15158 N/m^2
