What mass of ko2 in grams is required to react with 8.90-l, Ask an Expert

Academics

A self contained breathing apparatus use canisters containing gaining potassium superoxide.The superoxide reacts with the co2 exhaled by a person and replaces it with oxygen.

4KO(s) + 2CO2(g)--2K2CO3(s)+3O2(g)

what mass of KO2 in grams is required to react with 8.90-L of CO2 at 22.0 C and 767mm Hg? first calculate the number of moles of CO2 (R=0.08026 L*atoms/ mol*K) find moles of Co2 and mass of KO2 in grams?
