Problem: If you combine 25.1 g of a solute that has a molar mass of 25.1 g/mol with 100.0 g of a solvent, what is the molality of the resulting solution?

FREE Expert Solution

We’re being asked to calculate for the molality of an aqueous solution prepared by dissolving 25.1 g of solute in 100.9 g solvent


When calculating for molality, we use the following equation:

Molality (m)=moles of solutekg of solvent


We will calculate the molality of the solution using the following steps:

Step 1Calculate the moles of solute

Step 2: Calculate the mass of solvent in kg

Step 3: Calculate the molarity of the solution


Step 1: Calculate the moles of solute using molar mass
