\(n_{CaCO_3}=\dfrac{6}{100}=0,06mol\)
\(n_{CH_3COOH}=\dfrac{200}{60}=3,33mol\)
\(2CH_3COOH+CaCO_3\rightarrow\left(CH_3COO\right)_2Ca+CO_2+H_2O\)
3,33 > 0,06 ( mol )
0,06 0,06 0,06 ( mol )
\(V_{CO_2}=0,06.22,4=1,344l\)
\(m_{\left(CH_3COO\right)_2Ca}=0,06.158=9,48g\)
\(m_{ddspứ}=200+6-0,06.12=205,28g\)
\(C\%_{\left(CH_3COO\right)_2Ca}=\dfrac{9,48}{205,28}.100=4,61\%\)
\(n_{CaCO_3}=\dfrac{6}{100}=0,06\left(mol\right)\\
n_{CH_3C\text{OO}H}=\dfrac{200}{60}=3,3\left(G\right)\\
pthh:CaCO_3+2CH_3C\text{OO}H\rightarrow Ca\left(CH_3C\text{OO}\right)_2+H_2O+CO_2\)
LTL : \(\dfrac{0,06}{1}< \dfrac{3,3}{2}\)
=> CaCO3 hết
theo pthh : \(n_{CO_2}=n_{CaCO_3}=0,06\left(mol\right)\)
\(\Rightarrow V_{CO_2}=0,06.22,4=1,344\left(l\right)\)
\(\Rightarrow C\%=\dfrac{6}{200}.100\%=3\%\dfrac{\dfrac{ }{ }C\dfrac{ }{ }\dfrac{ }{ }\dfrac{ }{ }\dfrac{ }{ }}{ }\%\)
