Solid lithium hydroxide is used to remove exhaled CO2 from space vehicles by forming lithium carbonate & liquid water What mass of carbon dioxide can be absorbed by 10.0 g of lithium hydroxide

Answer 1

Write the balanced equation:

2LiOH + CO₂ ==> Li₂CO₃ + H₂O ... balanced equation

Find moles of LiOH used:

10.0 g LiOH x 1 mol LiOH/23.95 g = 0.4175 moles LiOH

Find moles CO₂ equivalent to 0.4175 moles LiOH in balanced equation:

0.4175 mol LiOH x 1 mol CO₂/2 mol LiOH = 0.2088 moles CO₂

Convert to mass of CO₂:

0.2088 moles CO₂ x 44 g CO₂/mol = 9.19 g CO₂
