Explanations:
1) The formula for calculating the number of moles of a molecule is expressed as:
For Sucrose:
Mass of sucrose = Moles * Molar mass
Mass of sucrose = 3.322 * 342.3g/mol
Mass of sucrose = 1,137.1206rams
Mass of sucrose in mg = 1,137,120.6mg
For Potassium sorbate
Mass of potassium sorbate = Moles * Molar mass
Mass of potassium sorbate = 3.322 * 150.22 g/mol
Mass of potassium sorbate = 499.03084grams
Mass of potassium sorbate in mg = 499,030.84mg
For corn starch
Mass of corn starch = moles * Molar mass
Mass of corn starch = 3.322 * 692.7g/mol
Mass of corm starch = 2,301.1494grams
Mass of corm starch in mg = 2,301,149.4mg
The mass of each binder differs due to the type and amount of element each binder contains. Also, the molar mass of each of the binders differs. These differences in their molar mass cause a difference in the mass of each binder.
2) Manufacturers can decide to choose one binder over another due to the following reasons;
i) The binder must be easily compressible. Compressibility is required to form a stable, intact, and compact mass when pressure is applied
ii) The binder must have consistent weight and uniform strength. This is important in measuring the fluidity necessary for the production of the tablet.
iii) Since the essence of adding a binder to powder that is to be granulated is as a solution, hence the manufacturer must also check the particle size, hydrophobicity, and solubility in the binders since they are all important in assessing granulation.
