\(m_{CaCO_3\left(tt\right)}=10^6.90\%.80\%=720000\left(g\right)\rightarrow n_{CaCO_3\left(tt\right)}=\dfrac{720000}{100}=7200\left(mol\right)\)
\(PTHH:CaCO_3\underrightarrow{t^o}CaO+CO_2\)
\(\left(mol\right)\) \(7200\) \(7200\)
\(m_{CaO\left(tt\right)}=7200.56=403200\left(g\right)=403,2\left(kg\right)\)
Đổi 1 tấn = 1000kg
CaCO3 ---t*--> CaO + CO2
6,4mol.............6,4mol
mCaCO3 có trong 1000 kg đá vôi = 90/100 . 1000 = 900(kg)
=> m CaCO3 theo pt = (800.80)/100 = 640(kg)
=> nCaCO3 = 640/100 = 6,4(mol)
=> mCaO = 6,4 . 56 = 358,4(kg)
