81. 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 25 degrees C and 689 mmHg, how many grams of formic acid were consumed?
I keep getting 6.53 g but the book says 6.34 g.
