LiOH and NaOH can each react with CO2
to form the metal carbonate and H2O.
These reactions can be used to remove CO2
from the air in a spacecraft.
a. Write a balanced equation for each
b. Calculate the grams of NaOH and of
LiOH that remove 288 g CO2 from the air.
c. NaOH is less expensive per mole than
LiOH. Based on your calculations,
explain why LiOH is used during shuttle
missions rather than NaOH.

  • chemistry -

    2NaOH + CO2 ==> Na2CO3 + H2O

    Convert 288 g CO2 to moles. moles = grams/molar mass.

    Using the coefficients in the balanced equation, convert moles CO2 to moles NaOH.

    Convert moles NaOH to grams. g = moles x molar mass.

    You should be able to do the rest on your own. Post your work if you get stuck.
