Note Avogadro's number is 6.022 x 1023 atom/mol.
(a) calculate the number of moles of air in the ball at the specified temperature and pressure. Consider
the air in the ball to follow the ideal gas law.
PV = nRT
where P is the absolute pressure of the air in atm, V is the volume of the ball, T is the absolute
temperature in K, and R is the ideal gas constant.
