## Question:

A solution is made by dissolving 96.2 g of HI in 3.75 liters of water at {eq}\displaystyle 90^\circ C {/eq}. Given that the density of water at this temperature is {eq}\displaystyle 0.9585 \dfrac{g}{ml} {/eq}, find the following:

a) Molarity

b) Molality

## Molarity vs. Molality

While both molarity and molality measure the concentration of a solute in a given solution, they express this concentration differently. Molality expresses the concentration in terms of moles of solute per kilogram of solvent while molarity expresses the concentration in terms of moles of solute per liter of solution.
