Final answer:
To calculate the molality of a solution, we need the mass of the solvent. Without that information, we cannot answer the given question.
Step-by-step explanation:
To calculate the molality of a solution, we need to use the formula:
Molality = moles of solute / mass of the solvent (in kg)
In this case, the solute is sodium hydroxide (NaOH) and the solvent is water. We are given the density of the sodium hydroxide solution, which can help us calculate the mass of the solvent.
First, we need to convert the density from g/mL to kg/L by dividing by 1000. In this case, the density is 1.54 g/mL, so it is equivalent to 1.54 kg/L.
Next, we can calculate the mass of the solvent by multiplying the density by the volume of the solution. We are not given the volume of the solution, so we cannot calculate the mass of the solvent.
Unfortunately, we need the mass of the solvent to calculate the molality of the solution. Without that information, we cannot answer the given question.
