A #22.35*g# mass of an unknown compound consisting of potassium, chlorine, and oxygen, contained #7.13*g# of potassium, #6.47*g# of chlorine. What is its empirical formula?
As always, we divide each constitiuent mass thru by the ATOMIC mass of each constituent atom.
And now we divide thru by the LOWEST molar quantity, that of potassium/chlorine, to give an empirical formula of
How did I know that that there were
