Asample of a compound of xenon and fluorine was confined in a bulb with a pressure of 16 torr. hydrogen was added to the bulb until the pressure was 64 torr. passage of an electric spark through the mixture produced xe and hf. after the hf was removed by reaction with solid koh, the final pressure of xenon and unreacted hydrogen in the bulb was 32 torr. what is the empirical formula of the xenon fluoride in the original sample?

High-pressure liquid chromatography (hplc) is a method used in chemistry and biochemistry to purify chemical substances. the pressures used in this procedure range from around 500 kilopascals (500,000 pa) to about 60,000 kpa (60,000,000 pa). it is often convenient to know the pressure in torr. if an hplc procedure is running at a pressure of 1.03×108 pa , what is its running pressure in torr?
