While preparing a solution in the laboratory, for molarity the final volume is made up to what?
Answer and explanation
Correct answer: Up to the fixed mark
A molarity solution must have a known final volume because molarity is moles of solute per litre of solution. In a volumetric flask, the dissolved solute is transferred and solvent is added carefully until the calibration mark, usually at the stated temperature. Half-full, arbitrary, or mass-based levels do not establish the required volume.
