PTHH: KOH + HNO3 \(\rightarrow\) KNO3 + H2O
Theo pt: 0,056 .. 0,063 .... 0,101 ............. (kg)
Theo đề: ...? ........ ? ......... 1000 .............. (kg)
Đổi: 1 tấn = 1000kg
56g = 0,056kg
63g = 0,063kg
101g = 0,101kg
\(m_{KOH}=\dfrac{1000.0,056}{0,101}\approx554,46\left(kg\right)\)
\(m_{HNO_3}=\dfrac{1000.0,063}{0,101}\approx623,76\left(kg\right)\)
