Hi, Im stuck on this question:

The volume of a certain mass of gas is 150dm^3. The kelvin temperature of the gas is doubled and the pressure is halved. What is the volume of the gas now?

Use the ideal gas law:


PV=nRT


Rearrange to get V by itself:


V = \frac {nRT} P


Now if T is doubled and P is cut in half, what happens to V?
