(a) Interpretation: The mass of sodium sulfide required to react completely with 27.8 mL of 0.163 M silver nitrate needs to be determined. Concept introduction: The ratio of moles in which reactant reacts and products are formed in a reaction is called stoichiometric ratio. The molarity of solution is defined as number of moles of solute in 1 L of the solution. It is mathematically represented as follows: M = n V ( L ) Here, n is number of moles of solute in 1 L of the solution. For given mass of a solute, the number of moles can be calculated as follows: n = m M Here, m is mass and M is molar mass of the solute.
