An experiment in a general chemistry laboratory calls for a 2.00 m solution of hcl. how many ml of 11.9 m hcl would be required to make 250 ml of 2.00 m hcl?

The volume of concentrated solution required is 42 mL

Explanation:

To calculate the molarity of the diluted solution, we use the equation:

where,

are the molarity and volume of the concentrated solution

are the molarity and volume of diluted solution

We are given:

Putting values in above equation, we get:

Hence, the volume of concentrated solution required is 42 mL
