\(n_{HCl}=\dfrac{3,36}{22,4}=0,15\left(mol\right);n_{AgNO_3}=\dfrac{100.1,1.8\%}{170}=\dfrac{22}{425}\left(mol\right)\)
\(AgNO_3+HCl\rightarrow AgCl+HNO_3\)
Lập tỉ lệ: \(\dfrac{22}{425}< \dfrac{0,15}{1}\Rightarrow\)Sau phản ứng HCl dư
\(n_{HNO_3}=n_{AgNO_3}=\dfrac{22}{425}\left(mol\right)\\ m_{ddsaupu}=0,15.36,5+100.1,1-\dfrac{22}{425}.143,5=108,05\left(g\right)\)
\(C\%_{HNO_3}=\dfrac{\dfrac{22}{425}.63}{108,5}.100=3,02\%\)
