What volume of a 3.0 m stock solution of h2so4 is needed to prepare 2.8 l of a 1.6 m h2so4 solution?

The volume of stock solution needed is 1.5 L

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 volume of stock solution needed is 1.5 L

the correct answer is:

a. formation of precipitation
