(a)
Interpretation:
The maximum mass of the hydrochloride salt that can dissolve in 50.0 mL of water is to be calculated.
Concept introduction:
Density is defined as mass per unit volume. Mass and volume are physical quantities and the units of mass and volume are fundamental units. Density is the ratio of mass to the volume. The unit of volume is derived from the units of mass and volume. The SI unit of density is kg/m3. The formula to calculate density is,
Density=MassVolume (1)
(b)
Interpretation:
The more volume of water needed to dissolve the cocaine is to be calculated.
Concept introduction:

The unit of volume is derived from the units of mass and volume. The SI unit of density is kg/m3. The formula to calculate density is,
Density=MassVolume (1)
Stoichiometry of a reaction is utilized to determine the amount of any species in the reaction by the relationship between the reactants and products.
Consider the general reaction,
A+2B→3C
One mole of A reacts with two moles of B to produce three moles of C. The stoichiometric ratio between A and B is 1:2, the stoichiometric ratio between A and C is 1:3 and the stoichiometric ratio between B and C is 2:3.
The expression to calculate the moles of a solute when given mass and molecular mass of compound are given is as follows:
Moles=massmolar mass (3)
