alright don't quote me on this cause i'm only in year 8 but i sort of understand the question so i'll try to explain lol
equation:
Aqueous lithium hydroxide [LiOH (aq)] + carbon dioxide [CO 2] -> lithium carbonate [Li2CO3 (aq)] + water [H2O]
volume of carbon dioxide [CO2] in the spacecraft cabin: 2.4 x (10 to the power of 5) [ans: 240,000]
atmospheric pressure in the spacecraft cabin: 7.9 x (10 to the power of -3) [ans: 79/10,000] with 312 K (i have no idea what k is.. but, quora says it means equilibrium constant.. if that makes sense to you then yay! if not then i can't help sorry)
a solution of lithium hydroxide (unknown volume) was put into the cabin. after a while, the volume of carbon dioxide in the cabin dropped to 1.2 x (10 to the power of -4) [ans: 3/25,000]
question: how much lithium carbonate [Li2CO3] was formed?
...aaaaaand i can't help you any further because i haven't learnt this topic yet, and i'm fairly certain you need a formula to find the answer. you might be able to ask a friend for the formula.. idk. but good luck with your test
notes:
a) i'm 3 years below you so this might be 100% wrong seeing as i've never even heard of this type of question before. i just used my brain and what i could understand from the statement and came up with some equations and stuff that i rephrased so that it would seem simpler. i hope it does u-u
b) the multiplication answers were provided by my calculator which i think it pretty reliable

That's easy all what you have to do is first draw the reaction progress chart and then find x (max)

atm is a unit that's used to measure atmospheric pressure

tbh when i searched up atm that was the first result but then i realised i should probably add "science meaning" after it xd
