Question

A container has a volume of `48 L` and holds `6 mol` of gas. If the container is compressed such that its new volume is `24 L`, how many moles of gas must be released to maintain a constant temperature and pressure?

Answer 1

We must release `3` moles

Explanation:

As temperature and pressure is constant and volume has been reduced from `48L` to `24L`, number of moles will also reduce from `6` `mol` proportionately to `3` moles.

Hence, we must release `6-3=3` moles.
