To calculate the molarity (M) and molality (m) of a 16% aqueous methanol (CH₃OH) solution by volume, we can follow these steps: ### Step 1: Determine the volume and mass of methanol and water in the solution. Given that the solution is 16% methanol by volume, this means: - Volume of methanol (CH₃OH) = 16 mL - Volume of solution = 100 mL The volume of water (H₂O) in the solution can be calculated as: ...
