Hey guys,(adsbygoogle = window.adsbygoogle || []).push({});

I am having a little problem with a problem I am doing in Physics (thermo chapter).

Well, here is the problem:

"The mass of the H2 molecule is 3.3e24 g. If 10e23 H2 molecules per second strike 2.0 cm^2 of wall at an angle of 55° with the normal when moving with a speed of 1.7 10e5 cm/s, what pressure in Pascals do they exert on the wall?"

I have attempted this problem numerous times for atleast 2 hours and 45 minutes and have not been able to get the correct solution.

I keep on getting 2.51e5 Pa but it is not correct.

If anyone could shed some light on this problem, I would greatly appreciate it!! I am more interested as to how you arrive to the solution rather that just an answer.

thanks,

joe
