Consider a height 170 m above the ground (which itself is 1247 m above sea level). If the temperature at this height is 10 C, what is the ratio of the density of this site compared to standard atmospheric conditions (hint - assume you can use the ideal gas law to calculate the density and then divide this value by the standard density value)? (answer to three decimal places)
