How Much CO2 Can 1.90kg of KO2 Absorb?

[lorka150]

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.
