Question
What will be the new concentration of PNP, if 30.5 uL of 2.15*10-4M PNP stock solution is mixed with 276.8 uL of water?
Report your numeric answer in the units of microMolar (uM)
would i divide the molarity by the total concentration

concentration is inversely proportional to the total solution volume
sean
so if the volume goes up the concentration will go down. Is there a formula to calculate this new concentration. I know there is m1v1=m2v2 and other ways to calculate this but it has been so long since i have seen any of this stuff im not really sure what route to go
Scott
as long as the amount of solute stays constant
molarity1 * volume1 = molarity2 * volume2
molarity1 * volume1 = molarity2 * volume2
