Đáp án đúng: B
Giải chi tiết:\(\begin{array}{l}{n_X} = 0,13\,mol\\\,\,\,\,\,\,\,\,{C_2}{H_8}{N_2} + {\rm{ }}2HCl \to {\rm{ }}{C_2}{H_{10}}{N_2}C{l_2}\\\,\,\,\,\,\,\,\,\,\,\,0,13\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, \to \,\,\,\,\,\,\,\,\,\,\,0,13\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,(mol)\\ \Rightarrow m = {m_{{C_2}{H_{10}}{N_2}C{l_2}}} = 17,29\,gam.\end{array}\)
Đáp án B
