\(n_{K2O}=\dfrac{23,5}{94}=0,25\left(mol\right)\)
a) Pt : \(K_2O+H_2O\rightarrow2KOH|\)
0,25 0,5
\(C_{MddKOH}=\dfrac{0,5}{0,5}=1\left(M\right)\)
b) Pt : \(2KOH+H_2SO_4\rightarrow K_2SO_4+2H_2O|\)
0,5 0,5
\(m_{ddH2SO4}=\dfrac{\left(0,5.98\right).100\%}{20\%}=245\left(g\right)\)
\(V_{ddH2SO4}=\dfrac{245}{1,14}=214,91\left(ml\right)\)
