CTHH: \(Na_xS_yO_z\)
\(n_{Na_xS_yO_z}=\frac{12,6}{126}=0,1\left(mol\right)\)
- Trong 0,1 mol hợp chất chứa:
\(n_{Na}=\frac{4,6}{23}=0,2\left(mol\right)\)
\(n_S=\frac{3,2}{32}=0,1\left(mol\right)\)
\(n_O=\frac{4,8}{16}=0,3\left(mol\right)\)
=> \(x:y:z=n_{Na}:n_S:n_O=0,2:0,1:0,3=2:1:3\)
=> CTHH: \(Na_2SO_3\)
