\(M_Z=\dfrac{5,05}{0,1}=50,5\left(g/mol\right)\)
\(m_{Cl}=\dfrac{50,5.70,3}{100}=35,5\left(g\right)\Rightarrow n_{Cl}=\dfrac{35,5}{35,5}=1\left(mol\right)\)
\(m_H=\dfrac{50,5.5,94}{100}=3\left(g\right)\Rightarrow n_H=\dfrac{3}{1}=3\left(mol\right)\)
\(m_C=50,5-35,5-3=12\left(g\right)\Rightarrow n_C=\dfrac{12}{12}=1\left(mol\right)\)
