Testing its ability to describe our vacuum distillation system requires an assumption in order to obtain a value for V g. The assumption is that V g is the volume that would contain, as a gas (at 760 mm Hg and 25 °C), the amount of water vaporized during a vacuum distillation. The amount of water vaporized was experimentally found to be 0.108 g.
