How many molecules of water are present in a room

1.The relative humidity of air is equal to the ratio of thepartial pressure of water in the air to the equilibrium vaporpressure of water at the same temperature. If the relative humidityof the air is 45%
and its temperature 23 degrees in celsius, how many molecules of water are present in a room measuring 12 ft by 9.0 ft by 8.0 ft?

2.A flask of water is connected to a vacuum pump. A fewmoments after the pump is turned on, the water begins to boil.Then, a few minutes later, the water begins to freeze. Explain what happened.
