Potassium superoxide (KO2)reacts in the following equation:
4KO2 + 2H2O +4CO2 =4KHCO3 + 3O2 If a person wearing an oxygen mask exhales 0.85 grams of CO2 every minute, how many moles of KO2 are comsumed every 10.0 minutes?

  • Chemistry (Stoichiometry) -

    .85g CO2 = 0.019 moles

    each mole of CO2 uses 1 mole KO2

    so, .019 moles/min * 10 min = 0.19 moles KO2
