SUMMARY

The discussion focuses on the absorption capacity of 1.90 kg of potassium superoxide (KO2) for carbon dioxide (CO2). The calculations confirm that 1.90 kg of KO2 can absorb approximately 0.588 kg of CO2 based on the stoichiometric relationships in the reactions provided. The molar masses used in the calculations are KO2 at 71.10 g/mol and CO2 at 44.01 g/mol. The inclusion of water in the reaction equations does not affect the final result due to the consistent molar ratios.

4KO2 + 2H2O --> 4KOH + 3O2
2KOH + CO2 --> K2CO3 + H2O

What mass of CO2 in kg can be absorbed by 1.90kg of KO2?

Molar masses are KO2 = 71.10g, CO2 = 44.01g
------------

So, would this make sense?
1.90kg KO2 x 1/71.10 x 4/4 x 56.11 = 1.499kg
then take that...
1.499g x 1/56.11 x 1/2 x 44.01 = 0.588kg (as the answer)



the 56.11 I had to figure out- they gave me the other molar masses...?

Thank you!

Why do you use water in reaction equations?

4KO2 + 2CO2 -> 2K2CO3 + 3O2

But it doesn't change final result, as molar ratio of 4KO2 and 2CO2 is identical. 0.588 is OK.
