\(n_{CO_2}=\dfrac{1,344}{22,4}=0,06\left(mol\right)\)
=> nC = 0,06 (mol)
\(n_{H_2O}=\dfrac{1,08}{18}=0,06\left(mol\right)\)
=> nH = 0,12 (mol)
\(n_O=\dfrac{1,16-0,06.12-0,12.1}{16}=0,02\left(mol\right)\)
\(n_{C_2H_2}=\dfrac{1,3}{26}=0,05\left(mol\right)\)
=> \(n_X=0,05\left(mol\right)\)
=> \(M_X=\dfrac{2,9}{0,05}=58\left(g/mol\right)\)
Xét nC : nH : nO = 0,06 : 0,12 : 0,02 = 3 : 6 : 1
=> CTPT: (C3H6O)n
Mà MX = 58 g/mol
=> n = 1
=> CTPT: C3H6O
