Final answer:
The concentration of the solution in mass percent is calculated by dividing the mass of the solute by the total mass of the solution, then multiplying by 100. For a solution with 41.2 g of C12H22O11 in 528 g of H2O, the mass percent is 7.24%.
Step-by-step explanation:
To calculate the concentration of a solution in mass percent, we need to use the formula: (mass of solute / mass of solution) × 100. Mass percent is a common way of expressing the concentration of a solution.
For the given problem:
- Mass of solute (C₁₂H₂₂O₁₁) = 41.2 g
- Mass of solvent (H₂O) = 528 g
Total mass of solution = mass of solute + mass of solvent = 41.2 g + 528 g = 569.2 g
To find the mass percent of C₁₂H₂₂O₁₁ in the solution:
(41.2 g / 569.2 g) × 100 = 7.24%
The concentration of the solution in mass percent is 7.24%.
