This answer can not be completed. The dimensions of the room are
needed. As well as the humidity. Is the air circulated or exhauseted.
These are needed becuase the humidity determins the evap rate. As well
as the exo process of the ethanol moving from the container to the the air fills with ethanol the rate at which the evaporation
occurs will change...
