alleryThe 'mass by mass percentage' of a solution is defined as:
A(Mass of solute / Mass of solution) × 100
BVolume of solute / Volume of solvent
CMass of solute × Mass of solvent
D(Mass of solvent / Mass of solute) × 100
Answer & Solution
Correct answer: A. (Mass of solute / Mass of solution) × 100
% m/m = (Mass of solute / Mass of solution) × 100. So a 5% m/m salt solution has 5 g salt in every 100 g of total solution (which means 5 g salt + 95 g water).
