How many milliliters of a 0.266 m kno3 solution are required to make 150.0 ml of 0.075 m kno3 solution?

The volume of required to make the unknown solution is 42.30 mL.

Explanation:

To calculate the volume required to make the given molar solution, we use the equation:

where,

are the molarity and volume of initial solution respectively

are the molarity and volume of final solution respectively.

We are given:

Putting values in above equation, we get:

Hence, the volume of required to make the unknown solution is 42.30 mL.

the answer is 303.15 or 303
