Calculation of Mass by Mass Percentage of a Solution
Mass by mass percentage is a way to express the concentration of a solution. It represents the ratio of the mass of the solute to the mass of the solution, expressed as a percentage.
Formula for Mass by Mass Percentage
The formula for mass by mass percentage is:
Mass by mass percentage = (mass of solute/mass of solution) x 100%
Calculation of Mass by Mass Percentage of the Solution
We are given that 25 grams of sugar is dissolved in 250 grams of water. The mass of the solution is the sum of the mass of the solute and the mass of the solvent:
Mass of solution = Mass of solute + Mass of solvent
Mass of solution = 25 g + 250 g = 275 g
Now, we can use the formula for mass by mass percentage to calculate the concentration of the solution:
Mass by mass percentage = (mass of solute/mass of solution) x 100%
Mass by mass percentage of sugar solution = (25 g/275 g) x 100% = 9.09%
Interpretation of the Result
The mass by mass percentage of the sugar solution is 9.09%. This means that 9.09% of the solution is made up of sugar by mass, while the remaining 90.91% is water by mass.
It is important to note that the mass by mass percentage is a relative measure of concentration. It does not give any information about the actual number of particles in the solution or their behavior.
