Question

What is the molality of a solution that has 6 mol of `CaCl_2` in 3 kg of water?

Answer 1

I think you should tell us the `"molality"`.

Explanation:

`"Molality" = "Moles of solute"/"Kilograms of solvent"`

You have the `"moles"`, you have the mass. So what's the `"molality"`?

Note that I would not expect this result to be terribly different from the `"molarity"`.
