Homework Help: Chemistry

Posted by Jeannie on Monday, October 29, 2012 at 6:33pm.

I conducted a lab in which I had to calculate the number of moles of water heated off from copper sulfate. I first weighed copper sulfide in a beaker to in order to get the amount needed to begin the heating of it. If the beaker was wet at the beginning of the experiment for the initial mass of the beaker, how would that affect the experimentally determined number of molecules of hydrate. Increase, decrease, or no affect?
