I interpreting my results for a thermal decomposition lab

[QUOTE="littlebearrrr, post: 4539871, member: 487953"] [h2]Homework Statement [/h2] I performed an experiment recently, which required me to heat a flask and an unknown compound to constant weight. The unknown was supposed to be a mixture of calcium sulfate dihydrate and NaCl. My goal for this lab was to determine the % NaCl in the mixture. My percent error wasn't too bad: I got 12%. I'm just curious as to what could have contributed to this, especially since this error was consistent among the rest of my lab group. (Note: I was sure to completely transfer all of my compound to my flask). Does it have anything to do with the hydrate not being completely driven off?
