Question

163. The total mass that the instrument can lift is the difference between the mass of air and the mass of the gas in the instrument, which corresponds to the volume of the instrument. Consider an instrument that can be heated to 65°C with an approximate diameter of 5.00 m. The ambient air temperature is 21°C. The pressure in the instrument is equal to the pressure in the atmosphere and is 745 torr. a. The total mass that the instrument can lift? Suppose that the average molecular weight of air is 29.0 g/mol (Hint: heated air is less dense than cold air). b. When the instrument is filled with helium at 21°C and 745 torr (equivalent to volume a), what is the total mass that the instrument can lift? c. If there is an instrument at Denver, Colorado, where the normal atmospheric pressure is 630. torr, what is the total mass that the instrument can lift?
