The mass of an aluminum boat is 4.9682 g. The mass of an aluminum boat and mixture of sand, NaCl, and (NH4)2CO3 is 6.5172 g. After sublimation of (NH4)2CO3, the mass of the boat and mixture is 6.1532 g. Water is added to the mixture and the resulting solution is filtered. After the sand is dried, the mass of the sand is 0.7648 g. After evaporation of the filtrate , the mass of salt is 0.4024 g. Calculate the % of sand, % of NaCl, and the % of (NH4)2CO3 in the mixture (show all calculations). Do these precentages add to 100%? if not, provide an explanation.
