Concentration InterconversionMediumQuestion 600046

Question

A 10% (w/v) NaOH solution means:
  1. A
    10 g NaOH per 100 mL solution
    Correct
  2. B
    10 g NaOH per 100 g solution
  3. C
    10 mol NaOH per litre
  4. D
    10 mL NaOH per 100 mL solvent

Correct answer

10 g NaOH per 100 mL solution

Explanation

%(w/v) = (mass of solute in g / volume of solution in mL) × 100. So 10% (w/v) = 10 g per 100 mL.
