Unformatted text preview: .859 atm 5. Which gas would you expect to behave more like an ideal gas, H 2 or HBr? (2 points) H 2 6. An oxide of nitrogen was found by elemental analysis to contain 30.4% nitrogen and 69.6% oxygen. If 23.0 g of this gas were found to occupy 5.6L at STP, what are the empirical and molecular formulas for this compound? (2 points) N 3 O 7 N 6 O 14 7. The gauge pressure in an automobile tire reads 32 pounds per square inch (psi) in the winter at 32 o F. The gauge reads the difference between the tire pressure and the atmospheric pressure (14.7 psi). In other words, the tire pressure is the gauge reading plus 14.7 psi. If the same tire were used in the summer at 110 o F and no air had leaked from the tire, what would be the gauge reading in the summer? (4 points) (Hint: o C = 5/9( o F 32)) 110 psi...
