More dilution problems
Here is some practice with different dilution schemes. This time the applet will do the counting for you. The first problem should be very easy at this point, but after that you can click on "Hard Problem" to get trickier dilution schemes.
And one problem you'll really need to think about...
Starting with a dilution made by a TA, you add 1 mL to 49 mLs of water to get a 1:500,000 dilution. What was the TA's dilution factor?
(To make this problem interactive, turn on javascript!)
- I need a hint ... :Your dilution factor is 1/50
- I need a hint ... : The overal dilution factor was 1/500,000
- ...another hint ... : 1/? * 1/50 = 1/500,000
I think I have the answer: 1/10,000
