Answer:

Are you asking for the molar mass of potassium permanganate, #KMnO_4#?

Explanation:

#KMnO_4#, which forms beautiful intensely purple crystals, has a molar mass of #158.03# #g*mol^-1#. In other words a mass of #158.03*g# of potassium permanganate has Avogadro's number of potassium permanganate formula units.

You should know how calculate that figure; it is a fairly trivial exercise that involves adding the molar masses of potassium, manganese, and #4# #xx# the molar mass of oxygen.
