Key Insights
To find the concentration of acid in the final mixture, scientists apply the principle of mass conservation. Multiply each solution’s volume by its concentration (expressed as a decimal), sum the total acid, then divide by the total volume. This method gives an accurate weighted average based on the volumes combined.
Calculating step by step:
- The first solution delivers: 40 mL × 0.30 = 12 mL of pure acid
- The second delivers: 60 mL × 0.50 = 30 mL of pure acid
- Total acid: 12 + 30 = 42 mL
- Total volume: 40 + 60 = 100 mL
- Resulting concentration: 42 mL acid ÷ 100 mL total = 42%
The final mixture is a 42% acid solution—balanced and measurable through consistent scientific methodology.
