m(CxHy) = 7 g
V(CO2) = 11.2 L
m(H2O) = 9 g
D(CxHy/CH4) = 4.375
-------------------------------
CxHy-?
M(CxHy) = D(CxHy/CH4) * M(CH4) = 4.375 * 16 = 70 g/mol
n(C) = n(CO2) = V(CO2) / Vm = 11.2 / 22.4 = 0.5 mol
n(H) = 2n(H2O) = 2n(m(H2O) / M(H2O)) = 2*(9/18) = 1 mol
n(C) : n(H) = 0.5 : 1 = 5 :10
C5H10
M(C5H10) = 12*5 + 1*10 = 70 g/mol
ответ C5H10
