To make a 4.00 M solution, how many moles of solute will be needed if 12.0 liters of solution are required?

To make a 4.00 M solution, 48 moles of solute will be needed if 12.0 liters of solution are required.

Explanation:

Molar concentration or molarity is a measure of the concentration of a solute in a solution, be it some molecular, ionic or atomic species.

Molarity is defined as the number of moles of solute that are dissolved in a given volume. Then it is calculated as the quotient between the number of moles of solute and the volume of solution:

Molarity is expressed in units .

In this case:

Replacing:

Solving:

4 M*12 liters= number of moles of solute

48 moles= number of moles of solute

To make a 4.00 M solution, 48 moles of solute will be needed if 12.0 liters of solution are required.
