FREE Expert Solution

We’re being asked to calculate the difference in volume between this solution and the total volume of the original unmixed liquids (methanol and water).

We're going to calculate the difference in volume using the following steps:

Step 1: Calculate the total volume of the original unmixed liquids.
Step 2: Calculate the mass of methanol.
Step 3: Calculate the moles of methanol.
Step 4: Calculate the volume of the solution.
Step 5: Calculate the difference in volume between this solution and the total volume of the original unmixed liquids.
