Concept explainers
(a)
Interpretation:
The solution having higher molarity needs to be determined.
Concept introduction:
Solutions are formed by homogeneous mixing of solute into a solvent. In the present case, solutes X and Y are dissolved using a solvent C to form a solution. Each case has its own uniqueness. The concentration of solutes and solvent should be defined in various terms to determine the strength of our solution through various angles.
Molarity is defined as ratio of number of moles of solute in a given volume of solution. It is represented by the unit “M”.
(b)
Interpretation:
The solution with higher mass percent needs to be determined.
Concept introduction:
Solutions are formed by homogeneous mixing of solute into a solvent. In the present case, solutes X and Y are dissolved using a solvent C to form a solution. Each case has its own uniqueness. The concentration of solutes and solvent should be defined in various terms to determine the strength of our solution through various angles.
Mass percent is defined as percent of mass of solute present in the solution.
(c)
Interpretation:
The solution having higher molality needs to be determined.
Concept introduction:
Solutions are formed by homogeneous mixing of solute into a solvent. In the present case, solutes X and Y are dissolved using a solvent C to form a solution. Each case has its own uniqueness. The concentration of solutes and solvent should be defined in various terms to determine the strength of our solution through various angles.
Molality of a solution is defined as number of moles of solute in 1 kg of the solvent.
(d)
Interpretation:
The solution having larger multiplier or i needs to be determined.
Concept introduction:
The multiplier is defined as the number of moles of particles of solution per mole of solute. In this case, this term can be redefined as the actual concentration of particle to the concentration of solute. The “particles” are the solutes X and Y in both cases. Hence, it is a relative ratio of concentration of solute molecules per mole of solute. Moles can be converted into molecules by multiplying it with
(e)
Interpretation:
The solution with solvent having higher mole fraction needs to be determined.
Concept introduction:
Mole fraction is a ratio of number of moles of one species with respect to total number of moles. In a solution, there is solvent and solute. Therefore, the number of moles of solvent and solute needs to be determined to obtain the total number of moles of solution.
