A molar solution is a solution that contains one mole of solute in

1 liter of the solution

Explanation:

Molarity or concentration of a solution refers to the number of moles of solute contained in a volume of 1 liter or 1 dm³ solution. Therefore, the concentration of a solution is calculated by dividing the number of moles of a solute by the volume of the solution. Concentration is given in mol/L or mol/dm³. Hence, a molar solution is a solution that contains 1 mole of a solute in 1 liter of the solution. This is equivalent to 1M or 1 mol/L.
