Notam substanta : Sx Oy Clz
d= M/M,H2------> rezulta masa molara a substantei ; M,H2=2g/mol
M= 2X67,5= 135 g/mol
Aflu din procente cate grame de sulf,oxigen si clor sunt in masa molara obtinuta
100g..........23,7gS.......23,7gO.........52,6gCl
135g ............a...............b.................c
a= 135x23,7/100=> 32g-S----> x,= 32g/32g/mol= 1
b identic 32gO----> y= 32g.16g/mol = 2
c= 135x52,6/100=71gCl-------> z=71g/35,5g/mol= 2
Substanta este SO2Cl2
