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 `32 L`, how many moles of gas must be released to maintain a constant temperature and pressure?

Answer 1

The number of moles is `=2mol`

Explanation:

We apply Avogadro's Law

`V_1/n_1=V_2/n_2`

The initial volume is `V_1=48L`

The initial number of moles is `n_1=6mol`

The final volume is `n_2=32L`

The final number of moles is

`n_2=V_2/V_1*n_1`

`=32/48*6=4 mol`

The number of moles to be released is `=6-4=2mol`
