PTHH: \(CaCO_3\xrightarrow[]{t^o}CaO+CO_2\)
Đổi 5 tấn = 5000 kg
Ta có: \(n_{CaO}=\dfrac{5000\cdot85\%}{56}=\dfrac{2125}{28}\left(kmol\right)=n_{CaCO_3\left(lý.thuyết\right)}\)
\(\Rightarrow m_{CaCO_3\left(thực\right)}=\dfrac{\dfrac{2125}{28}\cdot100}{90\%}\approx8432,5\left(kg\right)=8,4325\left(tấn\right)\)
