Example 1 It is known that the radius of the Earth is R = 6.4 × 106m, the gravitational acceleration of the Earth’s surface is g = 9.8 m/s2, the atmospheric pressure P0 = 1.0 × 105 Pa, and the average molar mass of air is M = 2.9 × 10-2 kg/mol. Vocardero’s constant NA=6×1023 mol. Other data can also be searched for in the exploration of the following problems.
