Unfortunately, a drop of water 0.125 cm3 in volume is left in the bottom of a screw hole. Due to the obstructed path to the pump, a negligible amount of water escapes during the early stages of pumpdown, and the drop becomes a virtual leak at a chamber pressure of 4.3E-06 torr. Find the volume of gas formed by the water at this pressure (assume it stays at room temperature). The density of water is 1g cm-3 and the molecular weight 18 g mole-1. (First, determine the number of moles in the drop of water, and use the ideal gas law to determine the volume)(b) To make this result clearer, what is the added time (in hours) to pump out this chamber due to this droplet if the pump, at that pressure, has a rate of 1480 L/s?
