Homework Help: N= cv

  1. Feb 10, 2009 #1
    c = 1mol/dm3

    v = 25cm3

    would i have to keep the units constant, as in multiply the 25cm3 by 1000??

    Thanks!

    Are there 1000 dm3 per cm3? I think not.

    You should keep the units consistant. Use either dm3 or cm3.

    If you feel confused in converting between the two, just do it at lower level:

    dm is 0.10 meter? cm is 0.01 meter.

    (1 dm)(1 dm)(1 dm)*(10 cm/1 dm)*(10 cm/1 dm)*(10 cm/1 dm)= what?

    but, i forgot whether M x cm^3 equaled to some other unit?

    It's also useful to keep in mind that 1 L = 1 dm3 and 1 mL = 1 cm3.

    Yes. One thousandth of the unit you will get from M x dm3.
