What is the mass of empty crucible and cover?
Well you see that the heat causes the crucible to blow up, almost causing an explosion. This then causes the MgNO4 gas to heat to it's 1.023 degree compound of 2 to the -2 power. The air inside of the metal makes the gas for the crucible go down and the mass changes in a way that is similar to a dog when he eats very hot grass on a very warm summer day (150 degree gas; 100 degree day). Hope this helps, Gilbert
