![**Determine the mass percent of a solution of sucrose (C₁₂H₂₂O₁₁) prepared by dissolving 3.245 g of C₁₂H₂₂O₁₁ in 73.5 g of water.**
### Explanation:
To calculate the mass percent of a solution:
1. **Determine the total mass of the solution:**
- Mass of sucrose = 3.245 g
- Mass of water = 73.5 g
- Total mass of solution = 3.245 g + 73.5 g = 76.745 g
2. **Use the formula for mass percent:**
\[
\text{Mass percent} = \left( \frac{\text{Mass of solute}}{\text{Total mass of solution}} \right) \times 100
\]
3. **Substitute the values:**
\[
\text{Mass percent} = \left( \frac{3.245}{76.745} \right) \times 100
\]
4. **Calculate the mass percent:**
\[
\text{Mass percent} \approx 4.23\%
\]
Therefore, the mass percent of sucrose in the solution is approximately 4.23%.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F04d91ec5-5dc8-475a-a219-706d13e893d1%2Fcaa43bf5-4468-4736-b3c1-2c05d520dffd%2Fyavecul_processed.jpeg&w=3840&q=75)
