Question

What pressure will be exerted by 2.01 mol hydrogen gas in a 6.5 L cylinder at 20°C?

Answer 1

`P=(nRT)/V=`, which equation is this? I get approx. `6*atm`

Explanation:

`P=(nRT)/V=(2.01*molxx(0.0821*L*atm)/(K^-1*mol^-1)xx293*K)/(6.5*L)`

`=??*atm`.

You should check to make sure that all the dimensions in the expression cancel to give an answer in `atm`. Does they?
