How to calculate volume of concentrated solution needed to prepare a diluted solution

Question

1) How many milliliters of the approximately 0.10 M prepared copper (I1) sulfate stork solution are needed to prepare 100.00 milliliters of a 0.010 M copper(Il) sulfate solution?

Answer 1

To calculate the volume of concentrated solution needed to prepare a diluted solution, you can use the formula:

M1V1 = M2V2

Where:
M1 = concentration of the concentrated solution
V1 = volume of the concentrated solution
M2 = concentration of the diluted solution
V2 = volume of the diluted solution

Given:
M1 = 0.10 M
V1 = unknown
M2 = 0.010 M
V2 = 100.00 mL

Plugging the values into the formula:

(0.10 M) * V1 = (0.010 M) * 100.00 mL
0.10 V1 = 1.00
V1 = 1.00 / 0.10
V1 = 10.00 milliliters

Therefore, you would need to measure out 10.00 milliliters of the approximately 0.10 M copper (I) sulfate stock solution to prepare 100.00 milliliters of a 0.010 M copper (II) sulfate solution.
