If 10 g of sugar is dissolved in 100 g of water, what is the mass percent of sugar in the solution? (2023)
Step 1: Identify the mass of the solute (sugar) which is 10 g.
Step 2: Identify the mass of the solvent (water) which is 100 g.
Step 3: Calculate the total mass of the solution by adding the mass of the solute and the mass of the solvent: 10 g + 100 g = 110 g.
Step 4: Use the mass percent formula: Mass percent = (mass of solute / total mass of solution) x 100.
Step 5: Substitute the values into the formula: Mass percent = (10 g / 110 g) x 100.
Step 6: Calculate the result: (10 / 110) x 100 = 9.09%.
Step 7: Round the result to the nearest whole number if needed: approximately 10%.
Mass Percent Calculation – Understanding how to calculate the mass percent of a solute in a solution by using the formula: (mass of solute / total mass of solution) x 100.
Total Mass Determination – Calculating the total mass of the solution by adding the mass of the solute and the mass of the solvent.
