(a) The number of molecules contained by the balloon at the given condition is 6,438.97 moles.
(b) The mass of air in the balloon is 186.73 kg.
The given parameters;
- <em>volume of the balloon, V = 1500 m³</em>
- <em>temperature, T = 10⁰C = 273 + 10 = 283 K</em>
- <em>pressure, = P = 10.1 kPa = 10,100 Pa</em>
The number of molecules contained by the balloon at the given condition is calculated as follows;
where;
- <em>R is ideal gas constant = 8.314 J/mol.K</em>
- <em>n is the number of moles air in the balloon;</em>
The mass of air in the balloon is calculated as;

Answer:
2.08×10^24 atoms
Explanation:
set up a mole to atom ratio:
3.47moles 1 mole
------------------ = ----------------------------
x atoms 6.02×10^23 atoms
cross multiply:
3.47 mole × 6.02 × 10^23 = 2.08×10^24 atoms
