Question

If formals of gas are added to a container that already hold one mole of gas, how will the pressure change with in the container?

Answer 1

The ratio of the pressures will equal the ratio of the molar change.

Explanation:

Assuming "Four Moles" was meant, the total new amount is 5 moles. From the Ideal Gas Law, at constant temperature:

`5/1 = P_2/P_1`

So the new pressure will be five times the original pressure.

`P_2 = 5 xx P_1`
