Per NCERT, the MASS BY VOLUME percentage (% m/v) formula is which expression?
A(Mass of solute in grams / Volume of solution in mL) × 100
B(Mass of solute / Mass of solvent) × 100
C(Volume of solute / Mass of solution) × 100
D(Volume of solution / Mass of solute) × 100
Answer & Solution
Correct answer: A. (Mass of solute in grams / Volume of solution in mL) × 100
% m/v = (mass of solute in g / volume of solution in mL) × 100 (per NCERT formula 5.2). The other options misstate.
