\(n_{SO_2}=\dfrac{5,6}{22,4}=0,25\left(mol\right)\)
nKOH = 0,3.1 = 0,3 (mol)
PTHH: 2KOH + SO2 --> K2SO3 + H2O
0,3-->0,15--->0,15
K2SO3 + SO2 + H2O --> 2KHSO3
0,1<--0,1----------------->0,2
=> hh muối gồm \(\left\{{}\begin{matrix}K_2SO_3:0,05\left(mol\right)\\KHSO_3:0,2\left(mol\right)\end{matrix}\right.\)
=> m = 0,05.158 + 0,2.120 = 31,9 (g)
