A hot-air balloon is filled with air to a volume of 4.00 × 103 m3 at 745 torr and 21oC. The air in the balloon is then heated to 62oC, causing the balloon to expand to a volume of 4.20 × 103 m3. What is the ratio of the number of moles of air in the heated balloon to the original number of moles of air in the balloon?
Answer to relevant QuestionsDetermine the partial pressure of each gas as shown in the figure below. The relative numbers of each type of gas are depicted in the figure. In a mixture of the two gases, the partial pressures of CH4(g) and O2(g) are 0.175 atm and 0.250 atm, respectively. a. What is the mole fraction of each gas in the mixture? b. If the mixture occupies a volume of 10.5 L at ...A compound contains only nitrogen and hydrogen and is 87.4% nitrogen by mass. A gaseous sample of the com-pound has a density of 0.977 g/ L at 710. torr and 100oC. What is the molecular formula of the compound? a. If the open-tube manometer in Exercise 22 contains a nonvolatile silicone oil (density = 1.30 g/cm3) instead of mercury (density = 13.6 g/ cm3), what are the pressures in the flask as shown in parts a and b in torr, ...Nitric acid is produced commercially by the Ostwald process. In the first step, ammonia is oxidized to nitric oxide: 4NH3(g) + 5O2(g) → 4NO(g) + 6H2O(g) Assume this reaction is carried out in the apparatus diagramed ...
