Question

In a spacecraft, the following reaction occurs:

CO2(g) + 2LiOH(s) -> LiCO3(s) + H2O(i) (i attached picture of equation)

how many liters of carbon dioxide will 4 moles of lithium hydroxide (LiOH) absorb? (One mole of any gads occupies 22.4 L under certain conditions of temperature and pressure. Assume those conditions for this equation.)

45L
6.0L
3.0L
34L

Answer 1

45L

Step-by-step explanation:

Answer 2

45.0 L.

Step-by-step explanation:

• According to the balanced equation:

CO₂(g) + 2LiOH(s) → Li₂CO₃(s) + H₂O(i).

Every 2.0 moles of LiOH absorb 1.0 mol of CO₂.

So, 4.0 moles of LiOH absorb 2.0 mol of CO₂.

Since, every 1.0 mole of a gas occupies 22.4 L.

∴ 2.0 moles of CO₂ will occupy (2 x 22.4 L) = 44.8 L ≅ 45.0 L.

∴ 4.0 moles of lithium hydroxide (LiOH) will absorb 45.0 L of CO₂.
