How many moles are in FE?
Divide the mass of iron by its molar mass in g/mol to get the moles of iron. One mole of anything is 6.022×1023 of anything, including atoms. Multiply mol Fe by 6.022×1023mol .
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.
