Answer : The mass of sample is 7.5 kilograms
Explanation :
Density : It is defined as the mass contained per unit volume.
Formula used :
Given :
Density = 3.00 g/mL
Volume = 2.50 L = 2500 mL
conversion used : (1 L = 1000 mL)
Now put all the given values in the above formula, we get:
conversion used : (1 kg = 1000 g)
Therefore, the mass of sample is 7.5 kilograms

Explanation:
The ternary constant is given by the following equation:
The symbol XiXi, where XX is an extensive property of a homogeneous mixture and the subscript ii identifies a constituent species of the mixture, denotes the partial molar quantity of species ii defined by
This is the rate at which property X changes with the amount of species i added to the mixture as the temperature, the pressure, and the amounts of all other species are kept constant. A partial molar quantity is an intensive state function. Its value depends on the temperature, pressure, and composition of the mixture.
In a multi phase system (in this case, a ternary system), the components resolved give:
and
Acetic acid (CH3COOH) is a weak acid while methylamine (CH3NH2) is a weak base. During an acid base reaction, an acid tends to lose a proton while a base tends to accept a proton. The reaction at equilibrium is as follows:
↔
Hence the species in equilibrium are:
Acetate anion: CH3COO-
Methyl ammonium cation: CH3NH3+
