\(2KOH+\left(NH_4\right)_2SO_4-^{t^o}\rightarrow2NH_3+2H_2O+K_2SO_4\\ n_{NH_3}=2n_{\left(NH_4\right)_2SO_4}=0,32\left(mol\right)\\ \Rightarrow V_{NH_3}=0,32.22,4=7,168\left(l\right)\)
\(n_{\left(NH_4\right)_2SO_4}=0,8.0,2=0,16\left(mol\right)\)
PTHH: \(2KOH+\left(NH_4\right)_2SO_4\rightarrow K_2SO_4+2NH_3+2H_2O\)
______________0,16----------------------->0,32
=> VNH3 = 0,32.22,4 = 7,168(l)
