Question

What is the volume expressed by a gas at an half atmosphere pressure..?

Answer 1

Solve the Ideal Gas equation for the different molar quantities, and of course you must specify a standard temperature........

Explanation:

We assume a molar quantity of gas, and we also assume ideality.

`V_n=(nRT)/P=(1*molxx0.0821*((L*atm)/(K*mol))xx298*K)/(0.5*atm)`

`=48.9*L`

So substitute in the other `P` values...........
