Homework Statement
0.20 g of hydrogen gas are held in a rigid container. The temperature of the gas is changed from 200 K to 320 K. How much heat is needed
2) A gas at p = 80kPa and T = 350K has a mass density of 8.65×10−2kg/m3 . find the V_rms
Homework Equations
E_thermal = 3/2nRT
2) v_rms = √(3k*T)/m
The Attempt at a Solution
tried doing this equation and got an answer of 30 which is wrong, not really sure if I am even on the right track any guidance is appreciated!
im not even sure how to start this problem, I am not sure the reason mass density is given, I am assuming to find mass but I am confused.
