Question: A hot air balloon is filled with air to a volume
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.
