It isn't K20.   It's probably either KCl or K2SO4.   Potassium content
is often expressed as K2O (Potassium Oxide).  The reason has something to
do with an old method of measuring a quantity of potassium by weighing it
after burning it.   At least that's what I vaguely remember from
chemistry class.
