Question

What is the total weight of CO2 expressed in kg that must be removed from the cabin on this journey? Four astronauts are going to make a voyage lasting 5 days. The carbon dioxide that they exhale must be removed from the cabin of the space craft, and a human body discharges about 9.60 x 10^2 g of CO_2/day. If the cabin of the space craft has a volume of 8.90 x 10^4 L and the partial pressure of CO_2 must be maintained at not more than the 4.1 torr at the cabin temperature of 27.0 ^degree C, what is the total weight of CO_2 ,expressed in kg, that must be removed from the cabin on this journey made by the four astronauts? Assume that the initial partial pressure of CO_2(g) in the cabin is zero at the start of the journey.

Explanation / Answer

m CO2 = 9.6*10^2 per day

t = 5 days

a) Total weigth of CO2 in kg

NOTE: initial P CO2 is 0

First calculate the total amount of CO2 in those 5 days

m CO2 in 5 days = 9.6*10^2 kg per day * 5 days = 4800 kg of CO2 need to be removed per person

But there are 4 persons so multiply by 4!

4800 kg * 4 = 19,200 kg of CO2 in total

All other data is extra data!
