Post by: superman on January 30, 2003, 09:47:00 AM

does anybody know approximately how much water there is in average w****rt acetone??? SWIM forgot to grab a drying agent and would like to wash a few grams of a water soluble substane without too much loss.   the substance is cheap, so some loss is acceptable

I wouldn't expect any anhydrous reagents out of a store like that. It's best to dry first.
