Ответ:
3.96 M
Explanation:
Step 1: Given data
Concentration of the concentrated solution (C₁): 8.9 MVolume of the concentrated solution (V₁): 76 mLConcentration of the diluted solution (C₂): ?Volume of the diluted solution (V₂): 171 mLStep 2: Calculate the concentration of the diluted solution
We can calculate the concentration of the diluted solution using the dilution rule.
C₁ × V₁ = C₂ × V₂
C₂ = C₁ × V₁/V₂
C₂ = 8.9 M × 76 mL/171 mL = 3.96 M
