WebWhat volume of a given 10 mM stock solution is required to make 20ml of a 50 μ M solution? Using the equation C 1 V 1 = C 2 V 2 , where C 1 =10 mM, C 2 =50 μ M, V 2 =20 … WebJan 3, 2024 · Example: 35 ml of 1.25 M HCl acid is needed to titrate a 25 ml solution of NaOH. In that case, you can use the 1:1 formula because one mole of HCl reacts with one mole of NaOH. Then, multiply the molarity of the acid by the volume of the acid – 1.25 * 35 = 43.75 and the result, by the volume of the base. cooley road beaver dams ny
