Earth has seasons because its axis is tilted.
The law of conservation of mass states that atoms cannot be created not destroyed, so they could not have destroyed it. This means that the experiment had to be open (which means there is no barrier that keeps all the solution in, like a plug or a bag). When the liquid in the equation turned into gas, the gas floated away from the solution, making the ending mass smaller than the beginning.
