Density of a $2.05 \mathrm{M}$ solution of acetic acid in water is $1.02 \mathrm{~g} / \mathrm{mL}$. The molality of the solution is

• A

  $1.14 \mathrm{~mol} \mathrm{~kg}^{-1}$
• B

  $2.28 \mathrm{~mol} \mathrm{~kg}^{-1}$
• Correct answer
  C

  $3.28 \mathrm{~mol} \mathrm{~kg}^{-1}$
• D

  $0.44 \mathrm{~mol} \mathrm{~kg}^{-1}$

Hence, the correct answer is option: 'C'.
