How many moles of K are in 1 mole of KOH? The subscripts in the formula indicate moles of each element per mole of compound. KOH contains only one K, so a mole of KOH contains one mole of K.
How many atoms of K are in 1 mole of KOH? There are 6.022 × 1023 atoms of potassium in every mole of potassium. Since one mole of KOH contains one mole of K, the answer is 6.022×1023 atoms of K.
How many atoms of K are in 1 molecule of KOH? Molecules of KOH can exist in the gas phase, but when we're talking about solid KOH we really should say "formula unit" rather than molecule because this is an ionic compound built of K+ and OH- ions packed together in a 1:1 ratio. If KOH is a molecular formula, we can say that there is one atom of K per KOH molecule. If KOH is an empirical formula, there is one atom of K per formula unit of KOH.
