MX = 2.29 = 58 (g/mol)
\(m_C=\dfrac{82,76.58}{100}=48\left(g\right)=>n_C=\dfrac{48}{16}=4\left(mol\right)\)
\(m_H=\dfrac{17,24.58}{100}=10\left(g\right)=>n_H=\dfrac{10}{1}=10\left(mol\right)\)
=>CTHH: C4H10
\(M_X=29.2=58(g/mol)\)
Trong 1 mol X: \(n_C=\dfrac{58.82,76\%}{12}=4(mol);n_H=\dfrac{58.82,76}{1}=10(mol)\)
Vậy \(CTHH_X:C_4H_{10}\)
