Which information is necessary to determine the molarity of a solution if the chemical formula of the solute is known?
A)only the mass of solute dissolved
B)only the volume of solvent used
C)the molar mass of both the solute and the solvent used
D)the mass of solute dissolved and the volume of solvent added
E)the mass of solute dissolved and the final volume of the solution

Quizplus · Accepted Answer

Molarity is defined as the number of moles of solute per liter of solution. To find the molarity, you need the mass of the solute dissolved to calculate the moles of solute (using the molar mass from the chemical formula) and the final volume of the solution to determine the volume in liters.
