6. A certain mass of oxygen was collected over water when potassium chlorate was decomposed by heating. The volume of the oxygen sample collected was 720. mL at 25.0°C and a barometric pressure of 755 torr. What would the volume of the oxygen be at STP? (Hint: First calculate the partial pres- sure of the oxygen, using Appendix Table A-8. Then use the combined gas law.)

In a collision of sufficient force, automobile air bags respond by electrically triggering the explosive decomposition of sodium azide (NaN3) to its elements. A 69.9−g sample of sodium azide was decomposed, and the nitrogen gas generated was collected over water at 26°C. The total pressure was 748.5 mmHg. How many liters of dry N2 were generated?
A student obtained a mass of 0.266 g CO2 during his experiment. The atmospheric pressure was 751.6 mmHg and the laboratory temperature was 24.1 °C. The flask used in the experiment had a volume of 146.5 mL. Calculate the molar mass of CO2 from the data. Hint: You cannot use the molar mass of CO2 in your calculation since this is what you are looking for... You need to used the ideal gas law to determine the number of moles of CO2, then do the ratio of grams of CO2 over moles of CO2 to determine the experimental molar mass of CO2.
