W(C) = 54.55% = 0.5455
W(H) = 0.09% = 0.0909
W(O) = 36.36% = 0.3636
V(г) = 1 L
m(г) = 4 g
------------------------
CxHyOz - ?
находим молярную массу газа
M(CxHyOz) = m(g) * Vm / V(g) = 4*22.4 / 1 = 89.6 g/mol
CxHyOz / M(CxHyOz) = W(C) / Ar(C) : W(H) / Ar(H) : W(O) / Ar(O)
CxHyOz / 89.6 = 0.5455 / 12 : 0.0909 / 1 : 0.3636 / 16 = 4 : 8 : 2
