Hydrogen Chloride (HCl) Molecular Weight Calculation
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) Molecular Weight Calculation
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.

Molarity of 50% (w/w) Sodium Hydroxide (NaOH)
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.
