A student was given a sample mixture of salt and sand. The mass of the sample was 2.48 grams.  The student added water to the salt and sand mixture.  The salt dissolved.  After filtration and evaporation, the student recovered and dried the salt, and found that it had a weight of 0.52 grams.  The student dried the insoluble residue of sand and found that it weighed 1.57 grams.
