Given:
Total solution : 1000mL
Pure acetic acid = 26mL
To find:
The percent concentration of given solution.
Solution:
We know that,
[tex]\text{Percent concentration}=\dfrac{\text{Pure acetic acid}}{\text{Total solution}}\times 100[/tex]
Putting the given values, we get
[tex]\text{Percent concentration}=\dfrac{26}{1000}\times 100[/tex]
[tex]\text{Percent concentration}=\dfrac{26}{10}[/tex]
[tex]\text{Percent concentration}=2.6[/tex]
Therefore, the percent concentration of this solution is 2.6%.
