(a)
Interpretation:
The weigh/volume percent concentration of the ibuprofen needs to be determined.
Concept Introduction:
Weigh/volume percent is defined as grams of solvent dissolved in milliliters of the solution.
Here, m is mass of solute in grams and V is volume of solution in mL.
(b)
Interpretation:
The volume of suspension in milliliters in 2.5-tsp dose needs to be determined.
Concept Introduction:
The problem is solved using the unitary method. If the volume of suspension in 1 tsp is given, the volume in given tsp can be calculated by just multiplying the two values.
(c)
Interpretation:
The reason for the directions on the medicine to be shake will before using needs to be explained.
Concept Introduction:
Weigh/volume percent is defined as grams of solvent dissolved in milliliters of the solution.
Here, m is mass of solute in grams and V is volume of solution in mL.
