Discover the Density Delight!

How do we calculate the density of a solution?

Given information:

Mass of empty flask and stopper = 99.895 g

Mass of flask, stopper, and solution = 126.975 g

Volume of the solution = 20.0 ml

Calculation of Solution Density

Step 1: Calculate the mass of the solution.

Mass of solution = Mass of flask, stopper, and solution - Mass of empty flask and stopper

Mass of solution = 126.975 g - 99.895 g = 27.08 g

Step 2: Convert the volume of the solution to liters.

Volume of solution = 20.0 ml * (1 L / 1000 ml) = 0.02 L

Step 3: Calculate the density of the solution.

Density = Mass / Volume

Density = 27.08 g / 0.02 L = 1354 g/L

Therefore, the density of the solution is 1354 g/L.

Are you ready to dive into the exciting world of density calculations? Let's explore how to determine the density of a solution using a simple experiment involving a volumetric flask, unknown substance, and water. By following the steps outlined above, you can easily calculate the density of the solution in grams per liter.

First, we start by measuring the mass of an empty volumetric flask and stopper, which serves as the baseline for our calculation. Then, we add the unknown substance to the flask, followed by water to dissolve the substance completely, resulting in a solution with a total volume of 20.0 ml.

After reweighing the flask, stopper, and solution, we find the mass to be 126.975 g. By subtracting the mass of the empty flask and stopper from the total mass, we obtain the mass of the solution, which is 27.08 g.

Next, we convert the volume of the solution to liters by multiplying it by the conversion factor. Finally, we calculate the density of the solution by dividing the mass by the volume, giving us a density of 1354 g/L.

Through this delightful experiment, we have successfully determined the density of the solution with precision and accuracy. Now, you too can embark on the journey of exploring the fascinating world of density calculations!
