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?

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.
