What is the definition of molarity?

• The ratio of the component's mass to the solution's mass expressed as a percentage

• The number of moles of solute in exactly 1 liter of the solution

• The concentration of a solution formed by dissolving a liquid solute in a liquid solvent

• The ratio of a solute's mass to the solution's volume expressed as a percentage

What is the formula for calculating mass percentage?

• Mass percentage = (Volume of solute / Volume of solution) x 100%

• Mass percentage = (Number of moles of solute / Number of moles of solvent) x 100%

• Mass percentage = (Mass of component / Mass of solution) x 100%

• Mass percentage = (Number of moles of solute / Volume of solution) x 100%
