Mass of silver nitrate must be used to completely precipitate the chloride ion from the sample which contain 10.3 % chloride ion by mass should be calculated. Mass of silver chloride obtained should be calculated.
Moles represent numbers of molecules, and we cannot count molecules directly. In chemistry, we count by weighing. The process of using chemical equation to calculate the relative masses of reactants and products involved in a reaction is called stoichiometry. The balanced equation for a chemical reaction describes the stoichiometry of the reaction.
