Calculate the concentration in terms of mass by volume percentage ofthe solution containing 2.5 gms of potassium chloride in 50ml of KCl

To calculate the concentration in terms of mass by volume percentage, we need to determine the mass of potassium chloride in the solution and then express it as a percentage of the volume.

Step 1: Calculate the mass of potassium chloride in grams. Given that the solution contains 2.5 grams of potassium chloride, we don't need to perform any calculations in this step.

Step 2: Calculate the volume of the solution in milliliters. The volume of the solution is given as 50 ml.

Step 3: Calculate the mass by volume percentage. To calculate the mass by volume percentage, we divide the mass of potassium chloride by the volume of the solution and multiply by 100.

Mass by volume percentage = (mass of potassium chloride / volume of solution) x 100

In this case, the mass of potassium chloride is 2.5 grams and the volume of the solution is 50 ml.

Mass by volume percentage = (2.5 g / 50 ml) x 100

Step 4: Calculate the concentration. Now, we can substitute the values into the formula and calculate the concentration.

Mass by volume percentage = (2.5 g / 50 ml) x 100 = 5%

Therefore, the concentration in terms of mass by volume percentage of the solution containing 2.5 grams of potassium chloride in 50 ml of KCl is 5%.
