Question: Formic acid, HCHO2, is a convenient source of small quantities of carbon monoxide. When warmed with sulfuric acid, formic acid decomposes to give CO gas.

Formic acid, HCHO2, is a convenient source of small quantities of carbon monoxide. When warmed with sulfuric acid, formic acid decomposes to give CO gas.
HCHO2(l ) → H2O(l ) + CO(g)
If 3.85 L of carbon monoxide was collected over water at 25oC and 689 mmHg, how many grams of formic acid were consumed?
