\(m_{HCl}=36,5.\left(0,796.0,5\right)=14,527\left(g\right)\)
\(m_{H_2SO_4}=98.0,75.0,796=58,506\left(g\right)\)
\(m_{H_2}=\frac{4,368}{22,4}.2=0,39\left(g\right)\)
Áp dụng ĐLBTKL:
\(\Rightarrow m_{hh}+m_{axit}=m_M+m_{H_2}\Leftrightarrow m_M=m_{hh}+m_{axit}-m_{H_2}=26,43+14,527+58,506-0,39=99,073\left(g\right)\)
88,7 gam
Bảo toàn H: nH+=2nH2O+2nH2
⇒ nH2O = nO(oxit) = 0,6 mol
⇒ mKL = mhh đầu - mO (oxit) = 16,9g
⇒ mmuối = mKL + mCl + mSO4 = 88,7g
