How many particles are in .169 moles of Potassium Sulfide?!
What is the percent composition of sulfer in that same prolem?!

There are 6.02E23 molecules in 1 mole of K2S. There are three particles (2K and 1S in a molecule of K2S); therefore, there are three particles per mole of K2S.
%S = (atomic mass S/molar mass K2S)*100 = ?
