FREE Expert Solution

We’re being asked to calculate for the molality of a 6.35 M methanol (CH3OH) solution. 

When calculating for molality, we use the following equation:

molality m = mol solutekg solvent


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

Step 1: Calculate the mass of the solute.

Step 2: Calculate the mass of the solution.

Step 3: Calculate the mass of the solvent (in kg).

Step 4: Calculate the molality of the solution.

Solute → CH3OH

Solvent → water (H2O)
