Cough syrup contains pharmaceutical active ingredients that
suppress cough or serve as decongestant. Usually these active
ingredients are present in low concentrations. The rest the
cough syrup is water, glycerine, and flavoring to hide the taste of
the actual medication. In this exercise, let's call the active
ingredient "anticofizine" (molar mass = 226.747 g/mole).
Usually, one adult dose of cough syrup is 1 tablespoon, which is
14.79 mL).
Exactly 1.00 mL of cough syrup is placed into each of five
volumetric flasks. To each flask except the first one, increasing
amounts of anticofizine standard is added. Each flask is
diluted to exactly 50.00 mL. The signal for the anticofizine
in each flask is measured. and the resulting standard addition
calibration curve has a linear equation of Y = 0.178X+0.435.
The slope units are (milliMolar anticofizine)-1
Question: How many mg of anticofizine are in one 14.79
