2. P1 V1 / T1 = P2 V2 / T2

Remember that equation?

Good.

Now what you are simply told to find is V2

P1, V1 and T1 are given in 16(b)
P2 and T2 are given in 16(d)

So, do the maths to find V2.

In case you are wondering how V2 is the answer. Note that P1, V1 and T1 are the initial (former) gas conditions.

P2, T2 and V2 are going to be the new gas conditions at the top of the mountain.

Considering that you would be opening the canister into the air bag, in such a way that the gas in the canister now enjoys and fills up both the canister and whatever inflated room in the air bag, this volume becomes V2.
