\(d_{\dfrac{X}{kk}}=1,034\\ M_{kk}=29\left(\dfrac{g}{mol}\right)\\ \Rightarrow M_X=d_{\dfrac{X}{kk}}.M_{kk}=1,034.29=30\left(\dfrac{g}{mol}\right)\)
\(\Rightarrow m_C=\%C.M_X=80\%.30=24\left(g\right)\\ m_H=m_X-m_C=30-24=6\left(g\right)\)

\(M_X=1,034.29=30\left(\dfrac{g}{mol}\right)\)
\(m_C=\dfrac{30.80\%}{100\%}=24\left(g\right)\)
\(n_C=\dfrac{23}{12}=2\left(mol\right)\)
\(m_H=\dfrac{30.20\%}{100\%}=6\left(g\right)\)
\(n_H=\dfrac{6}{1}=6\left(mol\right)\)
