Empirical and Molecular Formulae
Today,ive learnt how to calculate the empirical formulae..1stly by stating the % by mass,Ar,No. of moles,Mole ratio & x4.Some how,i understood the rest except for the x4.[Why is there a need to x4?]  Also,now i know there is a general formula for complete combustion.. Yay! xD
