A self-contained breathing apparatus uses canisters of potassium
superoxide, KO2, which consumes
the CO2 exhaled by a person and replaces it with oxygen according
to the following reaction:
4KO2(s) + 2CO2(g) → 2K2CO3(s) + 3O2(g)
(a) What mass of KO2 in g is required to convert 6.30 L of CO2
at 21.0 oC and 656 mmHg into O2?
Answer _____________________
(b) What is the rms speed of an O2 molecule at -9.4 oC?
