Starting with the stock solution of 6.0 m, how many milliliters of 6.0 m sulfuric acid are needed to make 450 ml of 1.2 m solution? *

The volume of stock solution needed is 90 mL

Explanation:

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

where,

are the molarity and volume of the stock sulfuric acid solution

are the molarity and volume of diluted sulfuric acid solution

We are given:

Putting values in above equation, we get:

Hence, the volume of stock solution needed is 90 mL
