Molarity is considered as the number of moles of a compound that are present in a liter solution, while normality is the amount of solution present in gram equivalent of a solute weight in a one-liter solution. For example, if the molarity of a mercury solution is 1M, it simply means that there is 1 mole of sugar contained in every 1 liter of the solution. Here, you need to check the gram equivalent weight first and it is usually checked by the total number of ions that reacts and it could change as well based on the reaction. Normality (N) = Molarity (M) x number of equivalents. Acid and Base Solution Preparation It is calculated by dividing the molecular weight MW of an acid or base by the number of equivalents per normalit for that acid or base Equation 2. Therefore, the molarity decreases, and this way, molarity is dependent on temperature. The below equation will help you convert M to N. N = M*n Where, n = the number of equivalents Number of gram equivalents = weight of solute [Equivalent weight of solute]-1. Because the density of water is 1 kg/L, 0.5 liters of water is equal to 0.5 kg of water. To convert the normality of a solution to molarity and molarity to normality: Strength (gram/litre) = Normality X Equivalent = Molarity X Molar mass Normality X Equivalent = Molarity X Molar mass Normality / Molarity = Molar Mass / Equivalent 1 mole of an ion has the same amount as its 1 gram-ion mass.
