5. It is important that the flask is completely dry before the unknown liquid was added, so that water droplets do not vaporize as well and occupy the flask volume when heated. A typical single drop of water has a volume of approximately 0.05 ml. If the density of water is 1.0 g/ml, calculate: a) The number of moles of water present in this drop of water b) The volume that vapor from this drop would occupy if it were heated at 160 °C and 1.95 atm.
