Giải thích các bước giải:
$\left\{\begin{matrix}V_{O_2}=3,36l\\V_{SO_2}=6,72l\end{matrix}\right.$ `=>`$\left\{\begin{matrix}n_{O_2}=\dfrac{3,36}{22,4}=0,15(mol)\\V_{SO_2}=\dfrac{6,72}{22,4}=0,3(mol)\end{matrix}\right.$
`=>`$\left\{\begin{matrix}m_{O_2}=0,15×32=4,8(g)\\m_{SO_2}=0,3×64=19,2(g)\end{matrix}\right.$`=>m_(\text(hỗn hợp))=4,8+19,2=24(g)`
