\(n_{SO_2}=\dfrac{8,96}{22,4}=0,4\left(mol\right)\\ n_{KOH}=0,3.2=0,6\left(mol\right)\)
Xét \(T=\dfrac{0,6}{0,4}=1,5\) => Tạo cả 2 muối \(K_2SO_3,KHSO_3\)
PTHH:
\(2KOH+SO_2\rightarrow K_2SO_3+H_2O\)
0,6------->0,3------>0,3
\(K_2SO_3+H_2O+SO_2\rightarrow2KHSO_3\)
0,1<-----------------0,1------>0,2
\(\rightarrow m_{muối}=\left(0,3-0,1\right).158+112.0,2=54\left(g\right)\)
