It is filled with air (Mw = 28.97 g/mol). 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. R=8.314 J mol¹ K-¹ = 0.082 05 L atm mol-¹ K-¹ = 8.205 73 m³ atm mol-¹ K-¹ = 1.987 cal mol-¹ K-¹ = 62.363 mmHg L mol-¹ K-¹ = 1545.348 ft lb, lbmol¹ K¹ = 1.985 Btu lbmol-¹ R-¹ = 10.731 ft³ psi lbmol-¹ R¹
