Theo đề bài ta có :
\(mCaCO3\left(trong-\text{đ}\text{á}-v\text{ô}i\right)=\dfrac{90.1}{100}=0,9\left(t\text{ấn}\right)\) = 900 (kg)
Ta có PTHH :
\(CaCO3-^{t0}\rightarrow CaO+CO2\)
100kg----------->56kg--->44kg
900kg----------->xkg
=> x = \(\dfrac{900.56}{100}=504\left(kg\right)\)
Vì H = 80% nên
=> \(mCaO\left(th\text{ư}c-t\text{ế}-thu-\text{đ}\text{ư}\text{ợc}\right)=\dfrac{504.80}{100}403,2\left(kg\right)=0,4032\left(t\text{ấn}\right)\)
Vậy...........
