Determine the percentage of mass of the atmosphere that resides between sea level and a height of 26.9 km. Assume an average pressure of 1.00 atm at sea level and a temperature of the atmosphere of 15 °C. The average molar mass of air is 28.96 g/mol. You may or may not need Earth's radius, which is 6,371 km.
