a) Theo định luật bảo toàn khối lượng ta có:
\(m_A+m_{O_2}=m_{CO_2}+m_{H_2O}\)
b) Theo a) ta có:
\(m_{CO_2}+m_{H_2O}=28+96=124\left(g\right)\)
Mà \(\dfrac{m_{CO_2}}{m_{H_2O}}=\dfrac{22}{9}\)
\(\Rightarrow m_{CO_2}=\dfrac{124}{22+9}\times22=88\left(g\right)\)
\(\Rightarrow m_{H_2O}=124-88=36\left(g\right)\)

Mà \(\dfrac{m_{CO_2}}{m_{H_2O}}=\dfrac{22}{9}\)
\(\Rightarrow m_{H_2O}=\dfrac{124}{22+9}\times9=36\left(g\right)\)
\(\Rightarrow m_{CO_2}=124-36=88\left(g\right)\)
