One of the air-purification methods for enclosed spaces involves the use of "scrubbers" containing aqueous lithium hydroxide, which reacts with carbon dioxide to produce lithium carbonate and water: 2 LiOH(aq) + 2 CO2(g) →Li2CO3(s) + H2O(l) Consider the air supply in a submarine with a total volume of 2.25 ×105 L. The pressure is 0.9950 atm, and the temperature is 25°C. If the pressure in the submarine drops by 0.0100 atm as the result of carbon dioxide being consumed by an aqueous lithium hydroxide scrubber, how many moles of CO2 are consumed?

Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.
