Carbon oxide (carbon (II) oxide) can be purified of oxygen impurities by having it react with cobalt (II) oxide. If the impure carbon oxide contains a volume of 1.5% oxygen, and if it reacts with cobalt (II) oxide at 250 °C and 500 kPa, what mass of cobalt (II) oxide will be required to purify 1.00 x 105 L of carbon oxide?
