2.7 Kg of each of water and acetic acid are mixed. The freezing point of the solution will be –x °C. Consider the acetic acid does not dimerise in water, nor dissociates in water. \( x = \) ______ (nearest integer).
[Given: Molar mass of water = \( 18 \, \text{g mol}^{-1} \), acetic acid = \( 60 \, \text{g mol}^{-1} \) \( K_f \, \text{H}_2\text{O} = 1.86 \, \text{K kg mol}^{-1} \) \( K_f \, \text{acetic acid} = 3.90 \, \text{K kg mol}^{-1} \) Freezing point: \( \text{H}_2\text{O} = 273 \, \text{K}, \, \text{acetic acid} = 290 \, \text{K} \)]
