6-25. A mixture of gases contains 66.0 g CO2, 2.02 g of H₂, and 16.0 g of O₂. If the total pressure of the mixture is 725 torr, what is the partial pressure of each gas? 6-26. Air, by weight, is essentially a mixture of 79% N₂ and 21% O₂. Calculate the partial pressure of each gas at a total pressure of 99 kPakPa.
13 The air that we breathe is actually a mixture of mostly the following gases- 78% N2, 21% O2, and (<1.0%) CO2 and H₂O and constitute about 99% of the air mixture on a poor air quality day. That remaining, approximate 1% of the air is associated with trace amounts of air and particle pollutants that can affect air quality, especially on hot, summer days. Groups that can be affected by poor air quality include those who have asthma, heart disease, and chronic obstructive pulmonary disease (COPD).
