Molality (m) is defined as the number of moles of solute per kilogram of solvent.
First, determine the number of moles of solute (ethanol) using its molar mass. Then, calculate the molality using the formula:
[ \text{Molality (m)} = \frac{\text{Number of moles of solute}}{\text{Mass of solvent in kg}} ]
Finally, substitute the values to find the molality.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
