C1V1 = C2V2 is a simple formula, but it has a huge importance for chemistry students and for anyone working in the chemistry laboratory. Do a standard curve dilution with 1.5mg, 1.Omg, 0.75 mg, 0.5mg, 0.25mg, and Omg/ml samples. The dilution equation obeys the law of conservation, i.e., the total number of moles of solute (the substance being dissolved) is conserved during the dilution process. 256 I want to prepare a 10ml of a 20?g/mL working solution, by diluting 0.1% w/v stock solution. saved Show all calculations and remember units.
