As early as 1938, the use of NaOH was suggested as a means of removing CO2 from the cabin of a spacecraft according to the following reaction : NaOH+CO2 -> Na2CO3 + H2O.

If the average human body discharges
925. 0 g of CO2 per day how many moles of NaOH are needed each day for eacch person in the spacecraft?

    Balance the equation.
    2NaOH + CO2 ==> Na2CO3 + H2O

    Convert 925 g CO2 to moles. moles = grams/molar mass.

    Using the coefficients in the balanced, equation, convert moles CO2 to moles NaOH.
    Moles CO2 x (2 moles NaOH/1 mole CO2) = moles CO2 x 2 = ??moles NaOH
