Question

in a particular reaction. The quantitative study of the reactants required of
formed is called stoichiometry Using stoichiometric calculations, the amount of one or
more reactant(s) required to produce a particular amount of product can be determined
and vice-versa. The amount of substance present in a given volume of a solution is
expressed in number of ways. e.. mass per cent mole fraction molarity and molality
