**#11. Calculate the mass percentage of Na₂S₂O₃ in a solution containing 11.7 g of Na₂S₂O₃ in 44.3 g of water.**
Explanation:
This problem asks you to determine the mass percentage of sodium thiosulfate (Na₂S₂O₃) in a solution. To find the mass percentage, use the formula:
\[ \text{Mass Percentage} = \left( \frac{\text{mass of solute}}{\text{mass of solute} + \text{mass of solvent}} \right) \times 100\% \]
In this case:
- Mass of solute (Na₂S₂O₃) = 11.7 g
- Mass of solvent (water) = 44.3 g
Substituting these values into the formula will give you the mass percentage of sodium thiosulfate in the solution.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F377a7caf-b074-415b-a7a2-489899521086%2F3103247d-b7e2-49e5-bc9b-e5b4060ded9e%2Fd2d5xt_processed.jpeg&w=3840&q=75)

Expert Solution
Step 1
Given that:
Mass of Na2 SO3 = 11.7 g
Mass of water = 443 g
Total mass of solution = mass of water + mass of Na2SO3
