The molarity of H 2 S solution is to be determined. Concept Introduction: The number of moles is calculated from the following expression: n = m M m …… (1) Here, m is the mass of solute, M m is the molar mass of solute, and n is the number of moles of the solute. The molarity of the solution is determined by the following expression: M = n V …… (2) Here, n is the number of moles of solute, V is the volume of the solution in liters, and M is the molarity of the solution.
