Solution: In order to find out Weight by weight percent you need to do :-

→ x/(x + y) × 100; where

  • x = solute
  • y = solvent
  • x + y = solution/compound

→ Weight of Mg/Weight of MgO × 100

→ 0.0976/0.1618 × 100

→ 60.32%

Different ways of finding out concentration are,

  • W/W % (No Unit)
  • Mole Fraction (No Unit)
  • Molarity (Unit is mol/l or M)
  • Molality (Unit is mol/kg or m)
  • Normality (Unit is N)
  • Formality (Unit is F)
