(a) Interpretation: The normality of the given solution is to be calculated. 25.2 mL of 0.105 M HCl diluted with water to a total volume of 75.3 mL. Concept Introduction: The atomic mass of an element is defined as the sum of number of protons and number of neutrons. Molar mass of an element is determined from atomic mass of an element. The number of moles is calculated by the formula, Moles = Mass g Molar mass The molarity is calculated by the formula, Molarity = Number of moles of solute Volume of solution L The normality of the solution is calculated by the formula, Normality = Molarity × Number of H + or OH − ions .
