WebJan 17, 2024 · Introduction. A Serial dilution is a series of dilutions, with the dilution factor staying the same for each step.The concentration factor is the initial volume divided by the final solution volume. The dilution factor is the inverse of the concentration factor. For example, if you take 1 part of a sample and add 9 parts of water (solvent), then you have … WebUse the gas constant that will give K_\text p K p for partial pressure units of bar. To solve this problem, we can use the relationship between the two equilibrium constants: K_\text p = K_\text c (\text {RT})^ {\Delta \text n} K …
