Is bsorbance molarity
Web26 jan. 2024 · Ans: Molarity is defined as the ratio of moles of solute to the volume of solution. By dividing the number of moles of \ ( {\rm {HCl}}\) by the volume \ (\left ( {\rm {L}} \right)\) of the solution in which it was dissolved, we will obtain the molarity of the \ ( {\rm {HCl}}\) solution. Q.4. How is the Molar Mass of a substance calculated?
