Physics rms speed question
Hi,
Please could I have some help on the following? I used the p=1/3Nm<c2>/v equation and took Nm as 3.2 because the mass of one particle times the number of total particles should give the total mass? But the answer is incorrect.

Thanks!

In my opinion, the original question is incomplete. The gas type and gas temperature are missing, so the problem cannot be solved.
I would like to remind you of what you can find in the link: Click Here
Correct me if I am wrong.
Thanks in advance.

by DrummyCorrect, you just missed out the three in the calculation but I tried it with and it’s the right answer. I went wrong by converting the 3.2 into grams, should it always be kg?

you don't need the gas type or the temperature
the rms speed is a function of the temperature

In fact, the "gas type" is given: the gas is monatomic and the mass is 3.20 kg.
While the temperature is defined by the given pressure and volume based on the ideal gas equation pV = nRT.
