The mass of thioridazine C 21 H 26 N 2 S 2 content in milligram on each tablet has to be determined. Concept introduction: The relation between the number of moles and mass of the substance is , N u m b e r o f m o l e = M a s s i n g r a m M o l a r m a s s M a s s i n g r a m o f t h e s u b s tan c e = N u m b e r o f m o l e × M o l a r m a s s The molar mass of an element or compound is the mass in grams of 1 mole of that substance, and it is expressed in the unit of grams per mol (g/mol). For chemical reaction balanced chemical reaction equation written in accordance with the Law of conservation of mass. Law of conservation of mass states that for a reaction total mass of the reactant and product must be equal. Stoichiometric factor is a relationship between reactant and product which is obtained from the balanced chemical equation for a particular reaction. Amount of substance = Concentration of substance × volume of the substance Mass percent of elements of a compound is the ratio of mass of element to the mass of whole compound and multiplied with hundred.

Chapter 4, Problem 128IL
Interpretation Introduction

Interpretation:

The mass of thioridazine C21H26N2S2 content in milligram on each tablet has to be determined.

 Concept introduction:

  • The relation between the number of moles and mass of the substance is ,

     Numberofmole=MassingramMolarmass

     Massingramofthesubstance=Numberofmole×Molarmass
