The reaction of potassium superoxide, KO 2 , is used in life-support systems to replace CO 2

Question:

The reaction of potassium superoxide, KO2, is used in life-support systems to replace CO2(g) in expired air with O2(g). The unbalanced chemical equation for the reaction is given below.

KO2(s) + CO2(g) → K2CO3(s) + O2(g)

(a) How many moles of O2(g) are produced by the reaction of 88.0 g CO2(g) with excess KO2(s)?

(b) How many grams of KO2(s) are consumed per 1.000 X 103 g CO2(g) removed from expired air?

(c) How many moles of K2CO3 are produced per milligram of K2CO3 consumed?
