The question:

Formic acid when warmed with sulfuric acid, decomposes to water and carbon monoxide.

HCHO2(l)-->H2O(l)+CO(g)

If 3.85L of carbon monoxide was collected over water at 25C and 589mmHg, how many grams of formic acid were consumed?
(This problem requires that you recognize the partial pressure of water is included in the 689mmHg and must be accounted for). (answer: 6.34g)

Can someone please help me with this, my teacher does not explain this well and I have a bunch of these kinds of questions, hopefully with steps on how to solve one I can figure the rest out?
