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?
WOW this question was from 2010 man if anyone sees my response than hello because this site seems inactive
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

To determine the number of moles of NaOH needed to remove the CO2 discharged by a person in a spacecraft, we'll follow these steps:
Step 1: Calculate the molar mass of CO2.
The molar mass of carbon dioxide (CO2) is the sum of the atomic masses of carbon (C) and two oxygen (O) atoms.
The atomic masses of C and O are:
- C: 12.01 grams/mol
- O: 16.00 grams/mol
Molar mass of CO2 = (2 * O) + C (since CO2 has two O and one C atom)
= (2 * 16.00) + 12.01
= 32.00 + 12.01
= 44.01 grams/mol
Step 2: Convert the amount of CO2 discharged by a person (925.0 g) to moles.
To convert grams of CO2 to moles, we'll use the molar mass of CO2.
Number of moles of CO2 = Mass of CO2 / Molar mass of CO2
= 925.0 g / 44.01 g/mol
Step 3: Calculate the stoichiometric ratio between NaOH and CO2.
From the balanced equation, we can see that for every one mole of CO2, one mole of NaOH is needed.
Stoichiometric ratio = 1 mole NaOH / 1 mole CO2
Step 4: Determine the number of moles of NaOH needed.
Multiply the number of moles of CO2 calculated in Step 2 by the stoichiometric ratio from Step 3.
Number of moles of NaOH = Number of moles of CO2 * Stoichiometric ratio
Now, you can substitute the values into the formula to find the number of moles of NaOH needed each day for each person in the spacecraft.
