Is there an equation used to fond remaining pressure
When CS2 at partial pressure 1930 torr reacts with H2 at partial pressure 8650 torr at constant volume and constant temperature according to the balanced equation, determine the partial pressure (atm) of H2 that remains.
CS2(g) + 4H2(g) → CH4(g) + 2H2S(g)

Bob Pursley worked this problem or one similar to it. Let me try to find that post and I'll give you a link.

This is close.
