Gọi Vdd là x
Ta có :
\(n_{HCl}=CM.V_{dd}=1x\)
\(n_{H2SO4}=CM.V_{dd}=0,5x\) BTNT: "H" \(n_{HCl}+2n_{H2SO4}=2n_{H2}\Leftrightarrow x+0,5x.2=0,24.2\) \(\Rightarrow x=0,24\) \(2n_{Zn}=2n_{H2}\Rightarrow n_{Zn}=0,24\left(mol\right)\) \(n_{HCl}=0,24.1=0,24\left(mol\right)\) \(n_{H2SO4}=0,24.0,5=0,12\left(mol\right)\) \(m_{muoi}=m_{Zn}+m_{Cl}+m_{SO4}\Leftrightarrow m_{muoi}=0,24.65+0,24.35,5+0,12.96\) \(\Rightarrow m=35,64\left(g\right)\)
