A balloon containing 0.600 mole of SO2 gas has a volume of 275 mL at a certain temperature and pressure. What volume, in milliliters, would a 0.765 mole sample of SO2 gas occupy at the same temperature and pressure conditions?

The easy way to do this is to recognize that volume is proportional to mols of gas at the same T and P or
(n1/v1) = (n2/v2) but an equally easy, but more work is to assume some value for T (any convenient numbers will work) and use PV = nRT, substitute the numbers and solve for P. Then using that value for P and the assumed value for T, use PV = nRT, substitute those numbers and solve for the new volume. You should get the same answer either way. Post your work if you get stuck.
