In many chemical applications, a mole is too big a unit to be easily manipulated. In those cases, centimoles =0.01 moles or millimoles =0.001 moles are used instead of a mole. The mass of a centimole of hydrogen is 0.01 g and of a millimole is 0.001 g or 1mg (one milligram). Moles of charge are the same as moles of anything else.
