Question

how many millimeters of the approximately 0.014 M copper (ll) sulfate solution are needed to prepare 100.00 milliliters of a 0.00028 M copper (ll) sulfate solution

Answer 1

To calculate the volume of the approximately 0.014 M copper (II) sulfate solution needed to prepare 100.00 milliliters of a 0.00028 M copper (II) sulfate solution, you can use the formula:

(Volume 1)(Concentration 1) = (Volume 2)(Concentration 2)

So, rearranging the formula, you can solve for Volume 1 (the volume of the 0.014 M solution):

Volume 1 = (Volume 2)(Concentration 2) / Concentration 1

Plugging in the values:

Volume 1 = (100.00 milliliters)(0.00028 M) / 0.014 M

Volume 1 ≈ 2.00 milliliters

Approximately 2.00 milliliters of the approximately 0.014 M copper (II) sulfate solution are needed to prepare 100.00 milliliters of a 0.00028 M copper (II) sulfate solution.
