Answer:
295.7 mL of 24% trichloroacetic acid (tca) is needed .
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 = 295.7 mL
295.7 mL of 24% trichloroacetic acid (tca) is needed .
Answer:
Explanation:
Hello,
In this case, the unit of concentration is molality which is defined by:
Whereas the mass of the solvent is measured in kilograms. In such a way, with the given data, we first compute the kilograms of water:
Then, we solve for the moles of the solute:
Finally since the molar mass of ethanol is 46 g/mol, we compute the grams for the given solution:
Best regards.
