\(n_{CaCO_3\left(bđ\right)}=\dfrac{1000.80\%}{100}=8\left(mol\right)\Rightarrow n_{CaCO_3\left(pư\right)}=\dfrac{8.75}{100}=6\left(mol\right)\)
PTHH: CaCO3 --to--> CaO + CO2
6------------->6
=> \(m_{CaO}=6.56=336\left(g\right)\)
\(m_{CaCO_3}=1000.80\%=800\left(g\right)\\ \rightarrow n_{CaCO_3}=\dfrac{800}{100}=8\left(mol\right)\)
PTHH: $CaCO_3 \xrightarrow{t^o} CaO + CO_2$
8------->8
$\rightarrow m_{CaO} = 8.56.75\% = 336 (g)$
Khối lượng đá vôi là: \(1\times80\%=0,8\)kg=800g
Ta có \(n_{CaCO3}=\dfrac{m}{M}=\dfrac{800}{100}=8\left(mol\right)\)
PTHH:\(\text{CaCO3→ CaO + CO2}\)
\(8\) 8 8 mol
\(\Rightarrow m_{CaO}=n\times m=8\times56=448g\)
