If 65.5 ml of hcl stock solution is used to make 450 ml of a 0.675 m hcl dilution, what is the molarity of the stock solution ?

The molarity of the stock solution is 4.64 M

Explanation:

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

where,

are the molarity and volume of the stock solution

are the molarity and volume of diluted solution

We are given:

Putting values in above equation, we get:  

Hence, the molarity of the stock solution is 4.64 M

the answer is minerals.
