Dilution (equation) - Wikipedia

WebSerial dilutions are created by taking a series of dilutions of a stock solution. The concentration decreases by the same quantity between each test tube. They can either be ‘doubling dilutions’ (where the concentration is halved between each test tube) or a desired range (e.g. 0, 2, 4, 6, 8, 10 mmol dm-3); Serial dilutions are completed to create a … Web7 de feb. de 2024 · solute volume = 1 liter / 4. solute volume = 0.25 liter.
