Question

LiOH reacts with CO₂ to form Li₂CO₃ (atomic mass of Li = 7). The amount of CO₂ (in g) consumed by 1 g of LiOH is closest to

(a) 0.916

(b) 1.832

(c) 0.544

(d) 1.088

Answer 1

Answer is : (a) 0.916

2LiOH + CO₂ → Li₂CO₃ + H₂O

Number of moles of LiOH = 1/24 moles

2 moles of LiOH reacts with 1 mole of CO₂ to form 1 mole of Li₂CO₃ and H₂O.

∴ Number of moles of
