A student leaves a 5 L beaker (1 foot high) containing 3 Lof ethyl ether (A) on their lab bench open to the atmosphere (we're in Boulder, CO). The lab temperature is 25C. Assuming that the ether evaporates through a stagnant layer of air in the beaker and is carried away once it reaches the top of the beaker, determine the initial mass flow rate of ether from the beaker (kg/hr). Given: Vapor pressure of ether at 25 C is 533 mmHg Diffusivity in air of 0.095 cm2/s MW of ethyl ether is 74.12g/mol. Density of ethyl ether is 0.7134 g/cm3 At Boulder atmospheric pressure is 624 mmHg
