PV = nRT

so, P1V1=P2V2   (since n, R and T are constants)


now  apply, enjoy and then "eat rainbows' !! :D

@apoorvk My chemistry is a bit rusty, so I'm curious to know - how would you go about solving this problem since it appears V1 is not given? Unless I am mistaken.

Aaha. no. your chem is not rusty, this problem has missing data. you need initial data. didnt't notice that earlier.
