Homework Help: Chemistry

Posted by Casey on Monday, July 12, 2010 at 9:33am.

If 10.0g of CaCl2 and 10.0g of NaCl are dissolved in 100.0mL of solution, what is the concentration of chloride ions?

I found the molar mass of CaCl2 is 111.0g/mol; the molar mass of NaCl is 58.44g/mol.

I divided 10g CaCl2/111.0g CaCl2
I divided 10g NaCl/588.44g NaCl and added the figures together and divided by .100L. The answer came out to 2.612057642. After comparing to my answer key, the answer is 3.51M. Can someone tell me what I'm doing wrong?
