Homework Help: First Year Chemistry

Posted by Joshua on Sunday, March 11, 2012 at 5:05pm.

I have a question that I don't understand from my first year chem lab.

Calculate the minimum volume of water needed to decompose all the excess Ethanoic Anhydride.
Recall: 1.0g of H2O = 1.0 ml of water.

How do I go about doing this?

what is the balanced equation involved?

(CH3CO)2O + H2O → 2 CH3CO-OH

so you have to know how much acetic anhydride you have, convert that to moles, and then you need the same number moles of water.
