calculate the volume of 17 M concentrated acetic acid solution that is needed to prepare 100 cubic centimeter of 1 M acetic acid?
What is the molarity of a 50.3-mL KNO3 solution which contains 1.24 g of KNO3?
To calculate the volume of a 17 M concentrated acetic acid solution needed to prepare 100 cubic centimeters of a 1 M acetic acid solution, we can use the equation:
M1 * V1 = M2 * V2
where
- M1 is the initial concentration of the concentrated solution (17 M),
- V1 is the volume of the concentrated solution we need to find,
- M2 is the final concentration we want to achieve (1 M),
- and V2 is the volume of the final solution (100 cubic centimeters).
Rearranging the equation to solve for V1:
V1 = (M2 * V2) / M1
Substituting the given values into the equation, we have:
V1 = (1 M * 100 cc) / (17 M)
V1 = 100 cc / 17
Calculating the result:
V1 ≈ 5.88 cubic centimeters
Therefore, you would need approximately 5.88 cubic centimeters of the 17 M concentrated acetic acid solution to prepare 100 cubic centimeters of a 1 M acetic acid solution.
