In a period of 0.9 s, 5.0  1023 nitrogen molecules strike a wall of area 9.0 cm2. If the molecules move at 280 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.)

Thank you for the opportunity to help you with your question!

pressure =force/area

4.68 x 10^-26 x10/0.0009

=5.2 x 10^-22
