How many milliliters of the approximately 0.15 M prepared copper (II) sulfate stock solution are needed to prepare 100.00 milliliters of a 0.015 M copper(Il) sulfate solution?
To calculate the volume of the stock solution needed to prepare the desired solution, we can use the formula:
M1V1 = M2V2
Where:
M1 = 0.15 M (concentration of the stock solution)
V1 = volume of the stock solution needed
M2 = 0.015 M (desired concentration)
V2 = 100.00 mL (final volume)
Plugging in the values:
0.15 V1 = 0.015 * 100
0.15 V1 = 1.5
V1 = 1.5 / 0.15
V1 = 10 mL
Therefore, you would need 10 milliliters of the approximately 0.15 M prepared copper (II) sulfate stock solution to prepare 100.00 milliliters of a 0.015 M copper (II) sulfate solution.
