1 tấn = 1000 kg
$CaCO_3 \xrightarrow{t^o} CaO + CO_2$
$n_{CaCO_3\ pư} = n_{CaO} = \dfrac{520}{56} = \dfrac{65}{7}(kmol)$
Suy ra:
$H = \dfrac{ \dfrac{65}{7}.100}{1000}.100\% = 92,86\%$
PTHH: \(CaCO_3\xrightarrow[]{t^o}CaO+CO_2\uparrow\)
Đổi 1 tấn = 1000kg
Ta có: \(n_{CaCO_3}=\dfrac{1000}{100}=10\left(kmol\right)=n_{CaO\left(lý.thuyết\right)}\)
\(\Rightarrow H\%=\dfrac{520}{10\cdot56}\cdot100\%\approx92,86\%\)
