Question

The pressure p of a gas as a function of its height is given by: \frac{d p}{d z}=-\frac{p m g}{R T} where z is the altitude, T is the temperature,

in K, m is the molar mass of the gas, g is acceleration due to gravity (9.81 m s2) and R is the gas constant(8.314 J mol-1 K-1). The pressure of the gas at 0 m altitude is 86,126.25 Pa. Calculate the presure of a gas with molar mass 630 g mol-1 when it has been raised to a height 5.5 m above the ground, at a temperature of 21.1 degrees celsius. Give your answer to 3 significant figures. Remember your units.
