    You have a stock solution of 100mM NaOH. What volumes would contain the following quantities?

    100µmol of NaOH. Volume of NaOH= .....µl
    (units in µl)



    Any help is appreciated as i am going around in circles!
    Please help with working, i am getting confused with all the units as they need to cancel out to get the final unit of µL.

    Many thanks!

     v = n/c = \frac{100*10^{-6}}{100*10^{-3}} = 0.001 L = 1000 µL

    µ = 1*10^(-6) => 1 µmol = 1*10^(-6) mol => 100 µmol = 100*10^(-6) mol
    m = 1*10^(-3) => 1 mM = 1*10^(-3) M => 100 mM = 100*10^(-3) M
