Solving NaCl Concentration Mixtures: What is the Result?
What NaCl concentration results when 269 ml of a 0.840 M NaCl solution is mixed with 617 ml of a 0.370 M NaCl solution?
Is it important to be aware of the final NaCl concentration when two solutions are mixed together?
Answer
When 269 ml of a 0.840 M solution of sodium chloride is combined with 617 ml of a 0.370 M NaCl aqueous solution, the result is 0.513 M of NaCl concentration.
When two solutions of different concentrations are mixed together, the resulting concentration can be calculated using the formula:
Strength = (V1S1 + V2S2)/(V1+V2)
By substituting the given values into the formula, we find:
Strength = (269*0.840 + 617*0.370)/(269+617) = 0.513 M
This calculation helps in determining the final concentration of the sodium chloride solution after mixing.
