\(n_{SO_3}=\dfrac{200}{80}=2.5\left(mol\right)\)
\(m_{dd_{H_2SO_4}}=1000\cdot1.12=1120\left(g\right)\)
\(m_{H_2SO_4}=1120\cdot17\%=190.4\left(g\right)\)
\(SO_3+H_2O\rightarrow H_2SO_4\)
\(2.5.....................2.5\)
\(m_{H_2SO_4}=2.5\cdot98+190.4=435.4\left(g\right)\)
\(m_{dd_{H_2SO_4}}=200+1120=1320\left(g\right)\)
\(C\%_{H_2SO_4}=\dfrac{435.4}{1320}\cdot100\%=33\%\)
$SO_3 + H_2O \to H_2SO_4$
$n_{H_2SO_4} = n_{SO_3} = \dfrac{200}{80} = 2,5(mol)$
$m_{dd\ H_2SO_4\ 17\%} =1000.1,12 = 1120(gam)$
Sau khi pha :
$m_{dd} = 200 + 1120 = 1320(gam)$
$m_{H_2SO_4} = 1120.17\% + 2,5.98 = 435,4(gam)$
$C\%_{H_2SO_4} = \dfrac{435,4}{1320}.100\% = 33\%$
