I had a solution of Acetic anhydride marked with 99.5% in the lab. I was supposed to find out the number of moles and weight. So I found out the density from Sigma-Aldrich (1.08g/1ml). I used 2ml so i multiplied 2mlX1.08 which gave 2.16 grams. But because it said 99.5%, should I multiply the 2.16 grams with 0.995?
I appreciate any help.
Thanks for reading.
