- Methyl mercaptan (methanethiol, CH:SH; MM = 48.11 g/mol) is an odorant used in natural gas mixtures containing methane (CH:; MM = 16.04). Use Graham's law of effusion to determine how many times faster than methyl mercaptan methane would diffuse from a pinhole leak in a natural gas line. A) 1.732 times faster B) 3 times faster C) 9 times faster D) 27 times fasterarrow_forward5. At 320 K and 16 bar, the molar volume of ammonia, NH3, is about 10% less than that of an ideal gas. The best explanation for this observation is: (a) The volume of an NH3 molecule is significant at this concentration. (b) The volume of an NH3 molecule is smaller than that of an ideal gas. (c) At this temperature, a significant amount of NH3 decomposes to N2 and H₂. (d) Intermolecular forces of attraction for NH3 become significant at this temperature and pressure.arrow_forwardExplain why the following phenomena occur in terms of which of the pressure P, volume V , number of moles of gas n, and temperature T are changing and which are staying constant, and state which of the gas laws - Boyle’s Law, Charles’ Law, and/or Avogadro’s Law - would describe each situation: (a) You press down on the handle of a bike tire pump, forcing air into a tire. (b) Boiling the water in a kettle causes gas to rush through the spout, producing a loud whistling sound. (c) The stream of gas leaving a compressed air can used for blowing dust off sensitive electronics feels cold even though the container is stored at room temperature. (d) Dropping a piece of solid zinc into a hydrochloric acid solution and fitting a balloon over the beaker causes the balloon to inflate. (e) Pulling the two halves of an accordion away from each other causes air to rush into the instrument.arrow_forward
