Answer 1

To calculate the final concentration of sulfuric acid in solution C, we need to consider the dilutions. By multiplying the initial concentration of H2SO4 by the dilution factors of each step, we can find the final concentration.

Step-by-step explanation:

The final concentration of sulfuric acid in solution C can be calculated by considering the dilutions. First, the 1.50 mL aliquot of 0.177 M H2SO4 is diluted to 10.0 mL, resulting in solution A. Then, a 10.0 mL aliquot of A is diluted to 50.0 mL, resulting in solution B. Finally, a 10.0 mL aliquot of B is diluted to 900.0 mL, resulting in solution C. Additional distilled water is added to C to reach a final volume of 1.0000 L. To find the final concentration of sulfuric acid in solution C, we can multiply the initial concentration of H2SO4 by the dilution factors of each step:

1. 
   
3. Step 1: Dilution factor for solution A = (10.0 mL / 1.50 mL) = 6.67
4. 
   
6. Step 2: Dilution factor for solution B = (50.0 mL / 10.0 mL) = 5.00
7. 
   
9. Step 3: Dilution factor for solution C = (900.0 mL / 10.0 mL) = 90.00

Now we can calculate the final concentration of sulfuric acid in solution C:

Final concentration of H2SO4 in solution C = Initial concentration of H2SO4 in solution A × Dilution factor for solution A × Dilution factor for solution B × Dilution factor for solution C
