\(n_{CO_2}=\dfrac{4.48}{22.4}=0.2\left(mol\right)\)
\(n_{NaOH}=\dfrac{8}{40}=0.2\left(mol\right)\)
\(T=\dfrac{0.2}{0.2}=1\)
\(\Rightarrow\text{Tạo muối axit}\)
\(NaOH+CO_2\rightarrow NaHCO_3\)
\(0.2...............0.2............0.2\)
\(m_{NaHCO_3}=0.2\cdot84=16.8\left(g\right)\)
Ta có: \(n_{CO_2}=0,2\left(mol\right)\)
\(n_{NaOH}=\dfrac{8}{40}=0,2\left(mol\right)\)
\(\Rightarrow\dfrac{n_{NaOH}}{n_{CO_2}}=1\) ⇒ Pư tạo muối NaHCO3.
PT: \(CO_2+NaOH\rightarrow NaHCO_3\)
___0,2________________0,2 (mol)
⇒ mNaHCO3 = 0,2.84 = 16,8 (g)

\(\dfrac{nNaOH}{nCO2}=\dfrac{\dfrac{8}{40}}{\dfrac{4,48}{22,4}}=1\)=>tạo muối NaHCO3
pthh CO2+NaOH->NaHCO3=>nNaHCO3=NCO2=0,2mol
=>mNaHCO3=0,2.84=16,8 g
