Determine the molality of a solution prepared by dissolving 7.16 g of potassium chlorate in 66.6 g of water. Give your answer to 2 decimal places.


We’re being asked to determine the molality of a solution prepared by dissolving 7.16 g of potassium chlorate in 66.6 g of water.

Recall that molality is the ratio of the moles of solute and the mass of solvent (in kilograms)

In other words:

Molality (m)=moles solutekg solvent
