A salt is analyzed and found to contain #0.92*g# of sodium, #1.42*g# of chlorine, and #2.56*g# of oxygen. What is the empirical formula of this salt?
Well, we find the molar quantities of each constituent.........to get an empirical formula of
Note that I DIVIDED THRU BY the ATOMIC MASS of each constituent. And now, we divide thru by the SMALLEST molar quantity, that of sodium, to get an empirical formula of
