Homework Help: chemistry

Posted by DrFunk on Tuesday, June 16, 2009 at 4:56pm.

How would I go about doing this question, can someone explain it step by step please, my answer I keep getting is 1.17m CaCl2, but the answer is 1.35m CaCl2?

A 1.30M solution of CaCl2 in water has a density of 1.1g/mL/ What is the MOLALITY?

Also, when for questions with relation to finding minimum pressure, or boiling point elevation or freezing point deperession quesitons, how do I know that I have to use the "i" factor or not?

Thanks
