đổi 22,4 cm3 = 0,0224 dm3
3360 cm3 = 33,6 dm3
\(n_{CO_2}=\dfrac{4,48}{22,4}=0,2\left(mol\right)\)
\(n_{N_2}=\dfrac{0,0224}{22,4}=0,001\left(mol\right)\)
\(n_{SO_3}=\dfrac{33,6}{22,4}=0,15\left(mol\right)\)
\(m_{CO_2}=0,2.44=8,8g\)
\(m_{N_2}=28.0,001=0,028g\)
\(m_{SO_3}=0,15.80=12g\)
\(m_{hh}=8,8+0,028+12=20,828g\)
