To compress a sample of gas from 2.5 litres at 1.8 atm pressure to a volume of 1.5 litres, what should the value of the pressure be increased to? The temperature remains constant.

My answer is 3 atm but I'm not too sure. Can someone check this. Thanks in advance for any help

at constant temp , pressure and volume are inversely proportional

2.5 * 1.8 = 1.5 * ?

3 looks good
