An airplane is pressurized to 650 mm Hg which is the atmospheric pressure at a ski resort at 13000 ft altitude If air is 21 percent oxygen what is the partial pressure of oxygen on the plane?
To find the partial pressure of oxygen, we first need to calculate the total pressure of the air in the airplane cabin using Dalton's law of partial pressures. Given that the atmospheric pressure at 13000 ft altitude is 650 mm Hg, the partial pressure of oxygen can be calculated as 21% of this total pressure since oxygen constitutes 21% of the air. Thus, the partial pressure of oxygen on the plane is: 0.21 * 650 mm Hg = 136.5 mm Hg.
How long is 2500 mm?
2500 mm is equivalent to 2.5 meters.
35 cm equals how much mm?
35 cm equals 350 mm, because there are 10 millimeters in one centimeter.
6.5 cm equals how many mm?
6.5 cm is equal to 65 mm. This conversion is based on the fact that 1 cm is equal to 10 mm.
What volume will 500 mL of gas at 20 c and a pressure of 420 mm Hg occupy if the temperature is reduced to 80 c and the pressure increased to 650 mm Hg?
To solve, use the combined gas law: (P1V1/T1) = (P2V2/T2). Plug in the initial conditions (P1 = 420 mm Hg, V1 = 500 mL, T1 = 20°C), and the final conditions (P2 = 650 mm Hg, T2 = 80°C) to find V2, the final volume. Remember to convert temperatures to Kelvin by adding 273 to the Celsius temperature.
