\(m_N=\dfrac{17.82,35}{100}=14\left(g\right)\Rightarrow n_N=\dfrac{14}{14}=1\left(mol\right)\)
\(m_H=\dfrac{17,65.17}{100}=3\left(g\right)\Rightarrow n_H=\dfrac{3}{1}=3\left(mol\right)\)
=> CTHH: NH3
\(Đặt:N_xH_y\left(x,y:nguyên,dương\right)\\ x=\dfrac{82,35\%.17}{14}=1\\ y=\dfrac{17,65\%.17}{1}=3\\ \Rightarrow CTHH:NH_3\)
