question

One problem concerning space flight is the removal of carbon dioxide (CO_2, molecular weight = 44.0 g / mole) emitted by the human body (about 924 g of CO_2 per day). One solution is to react CO_2 with sodium hydroxide (NaOH, molecular weight = 40.0 g / mole) to form water and sodium carbonate (Na_2CO_3, molecular weight = 94 g / mole) according to the followingreation: 2NaOH + CO_2 \ding{217} NaCO_3- + H_2O. How muchNaOHmust be carried on board a space capsule to remove the CO_2 produced by an astronaut on a 10 day flight?
