ok simple enough, if the question asked for moles of Cl would i just use 1M instead of .5M?
this is a stupid question but is it 3M because of the Cl2 and not just Cl?
Dr. Bob seriously you have saved me and I am very thankful that there are people like you out there who wish to help others!!!!!
I'm not sure the only help my professor gave for this question is as follows... Make a liter of 0.9%NaCl in water. The result for grams of NaCl to add to the water I want in one sig fig. Then use 600 mL of the 0.9% NaCl you prepared as the solvent to make
it doesn't say but I'm assuming its w/v
** Also need to prepare the 0.9% NaCl solution
thanks!!!! I realized i could get M from % and then followed the rest of your answer.
