Part A) A sample of a gas at 25°C and 1.0 atmpressure has a volume of 2.5 L. The container is allowed to expanduntil the pressure is 0.85 atm and the temperature is 15°C. Thefinal volume of the gas is __________ L.
Part B) A reaction is carried out that produceshydrogen gas. The gas is collected in an inverted beaker over waterat 25 oC. The vapor pressure of water at 25oC is 23.78 mmHg. The total pressure in the beaker isdetermined to be 755.3 torr. What is the partial pressure (in unitsof torr) of the hydrogen gas in the beaker?
Part C) CH3SH gas and NH3 gas both have strong distinctive odors. Ifcontainers of each of these two gases are opened at the front of aroom at the same time, which one will be smelled first by thepeople sitting in back of the room?
| A. | | CH3SH |
| B. | | NH3 |
| C. | | Since they are ate the same temperature they will both diffuseat the same rate so will be smelled at the same time. |
| D. | | Neither will diffuse to the back of the room so they will not besmelled by the people in the back of the room. |
