Chapter 2, Problem 25Q
Interpretation Introduction
Interpretation:
The volume of air in liters that might inhale in a typical day, air that is exhaled in a normal breath, breath per minute and air exhaled per day has to be calculated. This value has to be compared with the volume of air in a class room.
Concept Introduction:
Volume is the amount of space occupied by the matter.
The unit of volume is expressed in milliliters

1) A balloon filled with helium gas has a volume of 744 mL at a pressure of 1 atm. The balloon is released and reaches an altitude of 6.5 km, where the pressure is 0.5 atm. Assuming that the temperature has remained the same, what volume does the gas occupy at this height? Answer in units of mL.
2) A lungful of air (337 cm3 ) is exhaled into a machine that measures lung capacity. If the air is exhaled from the lungs at a pressure of 1.88 atm at 42.1 ◦C but the machine is at ambient conditions of 0.958 atm and 23 ◦C, what is the volume of air measured by the machine? Answer in units of cm3 .

QUESTION 20
In the experiment "Molar mass of volatile liquid", the pressure of the gas inside a flask was the same as atmosphere, and
the temperature was identical to the boiling water temperature of water bath. How did you measure the volume of the gas
inside the flask? -
O Read the volume written on the flask.
Fill the flask up to the brim with water and then transfer the water to a graduated cylinder.
Measure the volume of the liquid added to the flask before heating the sample.
Measure the volume of the liquid that condenses in the flask after cooling the sample.

- 2.) It’s a bad day in the lab! Two students are doing experiments. Each is 20 feet away from the professor. At the same time, each of them lets the same amount of a smelly gas into the room. One of them releases ammonia, NH3, and the other releases SO2. NH3 has a pungent odor, and SO2 smells like rotten eggs. The professor has no idea that this has happened, until she smell the first gas. Which chemical will the professor smell first? (NH3 or SO2) . If the professor starts to smell the first gas 42. seconds after the gas is released, how long will it take her to smell the second gas? sec. * Note: It is unsafe practice to work with these chemicals in an open lab.arrow_forwardThe volume of a gas is 4.98 L, measured at 1.00 atm.

Suppose that Charles had changed his plans and carried out his initial flight not in August but on a cold day in January, when the temperature at ground level was −10°C (14°F).
