Answer: 44.8 Liters
Explanation: According to law of conservation of mass, the sum of mass on the reactant side must be equal to the sum of mass on product side.
The balanced chemical equation is:
[tex]2LiOH+CO_2\rightarrow Li_2CO_3+H_2O[/tex]
Thus 2 moles of [tex]LiOH[/tex] absorb 1 mole of [tex]CO_2[/tex] i.e. 22.4 Liters at STP
4 moles of [tex]LiOH[/tex] absorb[tex]=\frac{22.4}{2}\times {4}=44.8Liters[/tex]
Thus 4 moles of [tex]LiOH[/tex] will absorb 44.8 L of [tex]CO_2[/tex]
