One method of removing CO2(g) from a spacecraft is to allow the CO2 to react with LiOH.

2LiOH(s)+CO2(g)---->Li2CO3(s)+H2O(l)

How many liters of CO2(g) at 25.5 degrees celsius and 749 Torr can be removed per 9kg of LiOH consumed?

1 answer

Convert 9 kg LiOH to moles. moles = grams/molar mass.

Using the coefficients in the balanced equation, convert moles LiOH to moles CO2.
Now convert moles CO2 to volume using
PV = nRT
