Question- If 2.0 x 10^23 argon atoms strike 4.0 cm^2 of wall per second at a 90 degree angle to the wall moving with a speed of 450 m/s. what pressure (in bar) does the gas exert on the wall? I got 1.5 x 10^3 but not sure I did it right.
Thoughtfully please put your best attempt to provide the solution of above problem
