What volume is needed to make a 4.0 molar solution holding 12 moles of solute? 3.0 liters 48 liters 12 liters 4.0 liters

Option (a) is the correct answer.

Explanation:

Molarity is defined as the number of moles present in a liter of solution.

Mathematically,       Molarity =

Since, it is given that molarity is 4.0 molar or 4.0 m/L and no. of moles is 12 moles.

Therefore, calculate volume as follows.

                      Molarity =

                         4.0 m/L =

                      volume = 3 L

Hence, we can conclude that volume of the given solution is 3 liters.
