\(n_{SO_3}=\dfrac{200}{80}=2,5\left(mol\right)\)
mdd H2SO4 17% = 1000.1,12 = 1120 (g)
=> \(m_{H_2SO_4}=\dfrac{1120.17}{100}=190,4\left(g\right)\)
PTHH: SO3 + H2O --> H2SO4
2,5------------>2,5
=> mH2SO4(sau pư) = 2,5.98 + 190,4 = 435,4 (g)
mdd sau pư = 200 + 1120 = 1320 (g)
\(C\%_{dd.H_2SO_4.sau.pư}=\dfrac{435,4}{1320}.100\%=32,985\%\)
