Homework Help: CHEMISTRY

Posted by cazzy on Friday, April 26, 2013 at 7:10pm.

Do you think it is more useful to have the percent by mass of water in hydrate or the percentage composition, assuming that you know the formula for the associated dehydrated compound?



Can someone please explain what's the meaning of this question, I'm confuse. Thanks!
