Calculate the volume needed of a stock (undiluted) solution that has a concentration of 4.2 M and is then diluted to 0.034 L of 0.66 M solution.

Sagot :

M1V1 = M2V2

V1(4.2) = (0.66)(0.034)

V1 = 0.0053L

The volume of undiluted solution or stock with the concentration 4.2 M is 0.005 L.

What is a diluted solution?

A solution is termed to be diluted when the concentration of the solute in the solution is decreased with the addition of solvent. The solution that is not diluted or prepared of specified concentration is termed as stock solution.

The volume of the stock solution prepared to form the dilute solution of 0.034 L of 0.66 M can be calculated as:

Molarity of stock * Volume of stock = Molarity of dilute * Volume of dilute

4.2 M * Volume of stock = 0.66 M * 0.034 L

Volume of stock = 0.005 L.

The volume of stock solution required to be produces is 0.005 L.
