Hello!

In a school’s laboratory, students require 50.0 mL of 2.50 M H2SO4 for an experiment, but the only available stock solution of the acid has a concentration of 18.0 M. What volume of the stock solution would they use to make the required solution?

0.900 mL

1.11 mL

6.94 mL

7.20 mL

We have the following data:

M1 (initial molarity) = 2.50 M (or mol/L)

V1 (initial volume) = 50.0 mL → 0.05 L

M2 (final molarity) = 18.0 M (or mol/L)

V2 (final volume) = ? (in mL)

Let's use the formula of dilution and molarity, so we have:      The volume is approximately 6.94 mL

The volume of stock solution of acid required 6.94 mL.

Explanation:

To calculate the volume of stock solution, we use the equation given by neutralization reaction: where, are the molarity and volume of acid which is  are the molarity and volume of stock solution of acid.

We are given: Putting values in above equation, we get: Hence, the volume of stock solution of acid required 6.94 mL.

Make More Than Just Soups

Chicken stock or broth can be used for all sorts of delicious dishes, not just soups and stews. From a cooking liquid for grains like rice and quinoa to a braising liquid for chicken or vegetables, it's a very useful ingredient that brings extra flavor to a recipe.
