Solid lithium hydroxide is used in space vehicles to remove exhaled carbon dioxide from the living environment. The products are solid lithium carbonate and liquid water. What mass of gaseous carbon dioxide can 1.00 x 10^3 g of lithium hydroxide absorb?

The LiOH can absorb 919.9 g of carbon dioxide.

The balanced equation is

##"2LiOH" + "CO"_2 → "Li"_2"CO"_3 + "H"_2"O"##

You must make the following conversions:

##"mass of LiOH" → "moles of LiOH" → "moles of CO"_2 → "mass of CO"_2##

##1.00 × 10^3 color(red)(cancel(color(black)("g LiOH"))) × "1 mol LiOH"/(23.95 color(red)(cancel(color(black)("g LiOH")))) = "41.8 mol LiOH"##

##41.8 color(red)(cancel(color(black)("mol LiOH"))) × ("1 mol CO"_2)/(2 color(red)(cancel(color(black)("mol LiOH")))) = "20.9 mol CO"_2##

##20.9 color(red)(cancel(color(black)("mol CO"_2))) × ("44.01 g CO"_2)/(1 color(red)(cancel(color(black)("mol CO"_2)))) = "919 g CO"_2##
