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
Answered by Scott
concentration is inversely proportional to the total solution volume
Answered by 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
Answered by Scott
as long as the amount of solute stays constant

molarity1 * volume1 = molarity2 * volume2
