## Homework Statement

Gas occupies 2m^3 at a pressure of 100kPa. What is the pressure when the volume is 1.5m^3 and the temprature is unchanged?

## Homework Equations

p=nRT/V

## The Attempt at a Solution

As a logic conclusion i took 1.5/2x100 and got 75 but 175 is not the answer.. The answer is 133kPa.

I also tried the p=nRT/V.

22.4l=1mol so 1500/22.4x1 is 66.96mol. (66.96x22.4x0)/1500=0

Can someone please tell me how to calculate this type of problem?

Thank you.
