If you start with a crucible that has a mass of 19.6g and you place calcium chloride into the crucible. You mass the crucible and contents and get 22.6g and then place it on the fire to heat for 25 minutes. It melts and begins to boil and a gas is given off while all you have left is a powdery mix. You let it cool and then find the crucible and powder now has a mass of 21.4g.
What is the mass of the new powder?
A.1.8 grams
B.1.2 grams
C.3.0 grams
D.63.6 grams
E.41 grams
