A relation known as the barometric formula is useful for estimating the change in atmospheric pressure with altitude. The formula is given by P = P0e-gmhyRT, where P and P 0 are the pressures at height h and sea level, respectively, g is the acceleration due to gravity (9.8 m/s2), m is the average molar mass of air (29.0 g/mol), and R is the gas constant. Calculate the atmospheric pressure in atm at a height of 5.0 km, assuming the temperature is constant at 5°C and P0 = 1.0 atm.
