Serial Dilution

Quickies

Below, you can practice a couple more times. I also included a few unusual situations ... things do go wrong, of course, and you should be able to recognize that. If you think the dilution series is not valid, click on "re-do the dilution". Oh, and "TNTC" means "too numerous to count".
