dessskris Posted November 16, 2011 Report Share Posted November 16, 2011 well how did you conduct the experiment? there are lots of ways you could know the amount of water, but that depends on your procedures. Reply Link to post Share on other sites More sharing options...
Sleeping Beauty Posted November 17, 2011 Report Share Posted November 17, 2011 So just do the calculation for no. of moles mass/atomic massso if you have 100g of water you have about 5.5 mol of water, and if you have 2g of copper sulfate you have about 0.01 molyou don't need the ratio to calculate the no. of moles Reply Link to post Share on other sites More sharing options...
