You placed a sample of a hydrate of calcium chloride (CaCl₂) in a weighed test tube, and weighed the filled test tube. Then you heated it until no more water was evolved. After cooling, you weighed the test tube again. Mass of empty tube (g) 13.99 Mass of filled tube before heating (g) 18.09 Mass after cooling (g) 16.8 Calculate the following: Moles of water evolved
