The mass of salt recovered would be the same as the initial mass because salt does not evaporate.
Evaporation is a process in which a liquid changes its phase to gas or vapor. This is an endothermic process in which the liquid molecules absorbs energy and due to high energy, they leave the system. Daily life example of evaporation includes, a hot cup of coffee getting cold, clothes getting dry in sunlight, wet hair getting dry after some time, etc.
But here is the question about salts, as salts are not liquids so they cannot evaporate or we can say salts have no any gaseous form. So when water evaporates we can get the dissolved salt. The salty oceans are a common example of this question.
