What is the molar mass for K?
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 moles of potassium are contained in 100 g of potassium?
1 Expert Answer
We get 23.55%. In one mole or 166 g of KI, 23.55% of it is K. Therefore, in 100 grams of KI , 23.55% of it would be K, so 23.55 g of potassium are in 100 g sample of KI.
