Web7 apr. 2024 · In chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. The standard formula is C = m/V, where C is the concentration, m is the mass of the solute dissolved, and V is the total volume of the solution. WebAssay is nothing but content of the desired material in the given sample, assay can be calculated on two basis, by. 1) Titrations and. 2) HPLC / GC. Assay by Titrations = [Titrate value of (sample - blank) x M x F x 100 x 100 ] / [Ws x (100- LOD)] Where, M - Molarity of Volumetric Solution, Ws - Weight of solution, F - Factor for drug substance,
