Answer:
295.7 mL of 24% trichloroacetic acid (tca) is needed .
Step-by-step explanation:
Let the volume of 24% trichloroacetic acid solution be x
Volume of required 10% trichloroacetic acid solution =8 bottles of 3 ounces
= 24 ounces = 709.68 mL
(1 ounces = 29.57 mL)
Amount of trichloroacetic acid in 24% solution of x volume of solution will be equal to amount of trichloroacetic acid in 10% solution of volume 709.68 mL.
![x* (24)/(100)=709.68 mL* (10)/(100)](https://img.qammunity.org/2020/formulas/chemistry/high-school/pabeguc00imxqgh4oaeezlfd26zthzpwe2.png)
x = 295.7 mL
295.7 mL of 24% trichloroacetic acid (tca) is needed .
