Question

What is the molality of a solution containing 8 moles of solute in 3.2 kg of solvnent?

Answer 1

`"Molality"` `=` `2.5*mol*kg^-1`

Explanation:

`"Molality"` is given by the quotient `"Moles of solute"/"kilograms of solvent"`.

And thus we simply fill in the blanks, `(8*"mol")/(3.2*"kg")=2.5*"mol"*"kg"^-1.`
