Who are the experts Experts are tested by Chegg as specialists in their subject area. Express this pressure in torr and in atmospheres. A sample of oxygen gas has a volume of 26.7 L at 752 mmHg and 20 C. P 0.975 atm atm 760 mmHg x 1 atm 741 mmHg h 52 cmHg 10 mmHg x 1 cmHg gas atm 520 mmHg P P - h 741 mmHg - 520 mmHg 221 mmHg 2. (e) List three important assumptions in these calculations. A student reads a barometer in the laboratory and finds the prevailing atmospheric pressure to be 746 mmHg. Determine the pressure of the gas (in mmHg) in the diagram below, given atmospheric pressure 0.975 atm. How many of Mozart's molecules do we breathe in with every inhalation of air? Round off your answer to one significant figure. Perform each of the following unit conversions using the conversion factors given below:1 atm 760 mmHg 101.325 kPa (Round answer to 4 significant figures. (c) If Mozart's lifespan was exactly 35 years, what is the number of molecules he exhaled in that period? (Given that an average person breathes 12 times per minute.) (d) Calculate the fraction of molecules in the atmosphere that was exhaled by Mozart. In one experiment it is found that at $850^$, which is the body temperature. 745 milímetros de mercurio 993.252 millibar. 745 milímetros de mercurio 745 mmHg 0 ☌s. What will the volume of the gas be at a pressure of 1. 745 milímetros de mercurio 10.1286 metros de columna de agua.
In time, a layer of the metal will deposit on the target area, and the variation in its thickness is found to correspond to Maxwell's speed distribution. A sample of gas has a volume of 250 cm3 when its pressure is 746 mmHg. Because the cylinder is rotating, atoms traveling at different speeds will strike the target at different positions. A small opening in the cylinder allows the atoms to strike a target area. Suppose that a beam of metal atoms is directed at a rotating cylinder in a vacuum. The following apparatus can be used to measure atomic and molecular speed. Click hereto get an answer to your question A gas occupies a volume of 250 ml at 745 mm Hg and 25 C. (mmHg Equation 5 Combined Gas Law As discussed in the previous section, the experiment allows for the determination of pressure, volume, and temperature of H 2(g).
