Question

What is the molality (m) of a solution that contains 76.5 g of KCl dissolved in 85.0 g of
water?

Answer 1

Answer:

76.5g KCl/74.55 grams per mole Kcl = x

molality= x/.085 kg H2O

Explanation:

well remember molality is moles of solute/kilograms of solvent. So it's the moles of KCl over 85 g of h20 converted into kg. if this makes sense.
