A student performed the experiment described in this module, using 6.00 mL of a 3% H2O2 solution with a density of 1.03 g mL-1. The water temperature was 22 ° C, and the barometric pressure in the laboratory was 30.30 in. Hg. After the student immersed the yeast in the peroxide solution, she collected 65.40 mL of O2. (3) Calculate the pressure, in torr, exerted by the collected O2 at the water temperature.

Photosynthesis by land plants leads to the fixation each year of about 1 kg of carbon on the average for each square meter of an actively growing forest. The atmosphere contains 0.0390% CO₂ by volume. What volume in (m³)of air (25°C, 1 bar) is needed to provide this 1 kg of carbon?
A manometer was connected to a bulb containing an unknown gas under slight pressure. The gas was allowed to escape through a small pinhole, and the time for the manometer reading to drop from 75 cm to 50 cm was 52 s. When the experiment was repeated using nitrogen (for which M = 28.02 g mol−1) the same fall took place in 42 s. Calculate the molar mass of the unknown gas. Hint: The pressure changes and, as a consequence, so does the rate of effusion; note, however, that the change is the same in both cases.

You and Liza Soberano are in an aircraft flying steadily at 4,300m above sea level and you are about to experience your first sky dive with her. You jumped first but Liza, due to hesitation, jumped after few seconds. Supposed that in an instant, the barometric pressure at your elevation is 85.0 kPa and Liza is higher from you by 800m. Determine the barometric pressure at Liza’s elevation assuming that pressure and temperature at sea level are 101.3 kPa and 25 deg.C respectively. Use lapse rate = 0.00650 K/m
