The pressure of 5.0 l of gas increases from 1.50 atm to 1240 mmhg. what is the final volume of the gas, assuming constant temperature?

First we need to convert everything into SI units.

The initial volume of the gas is (keeping in mind that :


The initial pressure of the gas is (keeping in mind that :


The final pressure of the gas is (keeping in mind that )


At constant temperature, the product between pressure and volume of the gas is constant, so we can write


from which we find the final volume of the gas:
