Hydrogen chloride (HCl) is an inorganic compound of two elements: hydrogen and chlorine. The hydrogen chloride molecular weight is the sum of hydrogen and chlorine atomic weights.

Acetic acid (CH3COOH) is an organic compound of three elements: Carbon, Hydrogen, and Oxygen. The molecular weight of Ethanolamine is 60.052 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

A 50% (w/w) concentrated Sodium hydroxide solution is a clear colorless liquid. It is an aqueous solution of Sodium hydroxide (NaOH). The 100 g of 50% Sodium hydroxide solution contains 50 g of NaOH. To calculate the molarity, one must first calculate how much Sodium hydroxide is present in 1 L of 50% Sodium hydroxide solution. Once we know the amount of Sodium hydroxide present in 1 L solution, we can calculate the molarity of the solution by dividing the NaOH amount by the molecular weight.
