Aqueous lithium hydroxide is used to purify air in space crafts and submarines because it can absorb the carbon dioxide that is exhaled: 2 LiOH(aq) + CO 2 (g) → Li 2 CO 3 (aq) + H 2 O(l). What volume of carbon dioxide can be removed from the cabin of a
spacecraft, which is kept at 25°C and 0.97 atm, if the gas reacts with a mass of 15.0 g of lithium hydroxide?
