In The Second Dilution
posted by Aminah on 09 May 2008 at 2:15 pm when we calculate dilution, we use V1C1 = V2C2 right? The thing that we need to find out if V1 correct? In the second dilution, what is the C1 that we use? is it the amount of concentration same as the first dilution or is it the dilution factor of the first dilution? |
