so i found the volume of SO2 to be 0.16695L using the ppmv (where V total mixture was 21L and V component/SO2 was what I solved for).

but i can't simply use P1V1=P2V2 (where 1=given condition, 2=SO2 conditions) because "n" isn't constant in both cases...

so how can I find the partial pressure of SO2?
