Question

A container has a volume of `24 L` and holds `32 mol` of gas. If the container is compressed such that its new volume is `14 L`, how many moles of gas must be released from the container to maintain a constant temperature and pressure?

Answer 1

The number of moles to be released is `=13.3mol`

Explanation:

We apply Avogadro's Law

`V_1/n_1=V_2/n_2`

Initial volume is `V_1=24L`

Final volume is `V_2=14L`

Initial number of moles is `n_1=32mol`

Final number of moles is

`n_2=V_2/V_1*n_1=14/24*32=18.7mol`

Number of moles to be released is `=32-18.7=13.3mol`
