Enter the mass of the beaker, the mass of the beak plus the solution, and the volume of the solution to determine the solution density.

Solution Density Formula

The following formula is used to calculate the density of a solution:

D = (MB+S – MB) / V

  • Where D is the density of the solution (g/cm^3)
  • MB is the mass of the of the beaker alone (g)
  • MB+S is the mass of the beaker plus the solution (g)
  • V is the volume of the solution (ml or cm^3)

Solution Density Defintion

What is a solution density?

A solution is simply a mixture of two or more liquid substances and a density a measure of the mass per unit volume. Therefore, a solution density is a measure of the mass of a mixture of solution per unit volume of that solution.

Example Problem

How to calculate a solution density?

The following example will outline the steps needed to calculate the density of a solution using the most common beaker method.

First, gather a beaker a measure is empty weight. For this example, the beaker is measure to be 15 grams.

Next, add the solution to the beaker and measure the weight. In this case, the combined weight is found to be 100 grams.

Next, measure the volume reading on the beaker. In this example, the beaker reads a total volume of 25ml.

Finally, calculate the solution density using the formula above:

D = (MB+S – MB) / V

D = (100 – 15) / 25

D = 3.4 g/ml = g/cm^3
