A student was asked to identify an unknown hydrate by following the procedure described in this module. After heating and cooling, a 2.752-g sample of this unknown weighed 1.941 g. Students were given a list of possible compounds from which to identify their unknowns: LiNO3 . 3 H20, Ca(NO3)2 . 4 H2O, and Sr(NO3)2 . 4 H2O.a) Calculate percent water in the students unknown.b) Could the unknown possibly have been Sr(NO3)2 . 4 H2O? Briefly explain.c) What is the probable identity of the students unknown?d) Based on the students results and your answer to (c), what is the most probable source of error in the experiment?
