Answer: b) the number of particles present in the solution
Explanation: Colligative properties are the properties which depends on the amount or the number of particles.
Colligative properties include relative lowering in freezing point,elevation in boiling point, depression in freezing point and osmotic pressure.
= osmotic pressure
C= concentration which depends on the amount or the moles of solute irrespective of its identity.
R= solution constant
T= temperature

Explanation:
The given data is as follows.
Density of vinegar = 1.0 g/ml
Specific heat capacity = 4.25
=
, and
=
Relation between enthalpy and specific heat is as follows.
Hence, putting the values into the above formula as follows.
= (as density =
)
= - 315 J
Thus, we can conclude that the enthalpy of reaction is -315 J.
As the value is negative so, it means that heat is releasing. Hence, the reaction is exothermic in nature.
