Hey guys I am having a small problem that I can not seem to get right.
Question: The chief ions in seawater are Na+, Mg2+, and Cl-. Seawater is approx. 0.438 M NaCl and 0.0512 M MgCl2. What us the mass Cl- (that is the total [Cl-] in seawater?
I know the procedure to calculate M, but when I write the balanced equation I keep getting 3 mols of Cl-.
NaCl + MgCl2 --h20 > Na+ + Mg2+ + 3Cl-
If someone could write the entire solution step by step that would be great.
Thanks in advance.
