Olympic cyclists fill their tires with helium to make them lighter. Assume that the volume of the tire is 855mL , that it is filled to a total pressure of 120psi , and that the temperature is 23 C. Also, assume an average molar mass for air of 28.8 g/mol. Part A: Calculate the mass of air in an air-filled tire.Part B: Calculate the mass of helium in a helium-filled tire.Part C: What is the mass difference between the two?

Helium-filled balloons rise in the air because the density of helium is less than the density of air.

(a) If air has an average molar mass of 29.0 g/mol, what is the density of air at 25°C and 770 mmHg?

(b) What is the density of helium at the same temperature and pressure?

Which of the following statements best explains why a closed balloon filled with helium gas rises in air?
(a) Helium is a monatomic gas, whereas nearly all the molecules that make up air, such as nitrogen and oxygen, are diatomic.
(b) The average speed of helium atoms is greater than the average speed of air molecules, and the greater speed of collisions with the balloon walls propels the balloon upward.
(c) Because the helium atoms are of lower mass than the average air molecule, the helium gas is less dense than air. The mass of the balloon is thus less than the mass of the air displaced by its volume.
(d) Because helium has a lower molar mass than the average air molecule, the helium atoms are in faster motion. This means that the temperature of the helium is greater than the air temperature. Hot gases tend to rise.

A balloon is filled with hydrogen gas and produces the followingchemical reaction between iron and sulfuric acid: Fe(s) + H2SO4(aq)--> FeSO4 (aq) + H2(g). If the balloon had a volume of 4800cubic meters and was filled to a pressure of 1 atm at a temperatureof 0 degrees C, a) what mass of iron (in kg) and how many moles ofsulfuric acid were required to fill it? b) If the total mass thatcan be lifted by a balloon is equal to the difference between themass of gas in the balloon and the mass of air displaced by theballoon, how much mass could by lifted by this balloon and how muchmass could the same balloon lift if it was filled with helium atthe same pressure and temperature. c) using the barometric formulaP= P(initial)e^(-mgh/kt) to estimate the height to which theballoon with a payload of 1000kg can rise when filled withhydrogen. (The balloon will rise until its density equals that ofthe surrounding air) Assume the the temperature of the air does notchange with the altitude. Use an average molar mass for the airbased on 80% N2, 20% O2.
