Sulfur dioxide ( SO2 ) is a gas that causes acid rain . At the disposal of the fumes found 24 L found in the SO2 gas pressure of 200 torr . If the pressure is changed to 500 torr at a constant temperature , the volume of SO2 gas berapakan now ?

I can't make sense of your post. You need to proof these things before posting. If you want the new volume, use p1v1 = p2v2
