Here's the question:
What is the boiling point of a solution that contains 1.25 mol [tex]CaCl_2[/tex] in 1400g of water?
Now, I know that I have to take into account the fact that [tex]CaCl_2[/tex] disassociates in water to form ions.
I thought the effective molality here would be 3 * 1.75 m since there are 3 ions. But, the book saids it's 2 * 1.75 m.
I'm confused as to why that is.
