The molarity of 25% (w/w) hydrochloric acid is 7.68 M. The 25% (w/w) hydrochloric acid contains 25g of HCl per 100g of solution. Since molarity is the number of moles of a substance present in a liter of solution, one must first calculate how much HCl is present in 1L of 25% hydrochloric acid solution. Once we know the amount of HCl present in 1L of solution, we can calculate the molarity of the solution by dividing the HCl amount by the HCl molecular weight.

Benzothiazole (C7H5NS) is an organic compound of four elements: Carbon, Hydrogen, Nitrogen, and Sulfur. The molecular weight of Benzothiazole is 135.18764 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.
