Mass about 20 kernels of popcorn in a dirty Erlenmeyer flask. Put some aluminum foil over the flask and poke a couple small holes in it. Heat the flask over the Bunsen Burner until all the kernels pop. Noteif it starts to burn before they all popstop anyway. Remove unpopped kernels before remassing. WHILE HEATINGCONSTANTLY MOVE THE FLASK AROUND ON THE WIRE GAUZE. USE CRUCIBLE TONGS TO HOLD THE FLASKDO NOT LEAVE IT SITTING ON THE WIRE GAUZE AT ANY TIME. When the flask is cooledre mass. Find the mass of water in the kernels by subtraction. Find the mass of the unpopped kernels by subtraction. Determine the percentage composition of water in the kernels. Repeat the entire procedure, average your data. _ hpS,#$fgrs b c / _ h^hgdpS, & FgdpS,_ ,1h/ =!"#$% @@@ NormalCJ_HaJmH sH tH DAD Default Paragraph FontRiR  Table Normal4 l4a (k@(No List_#$fgrsbc/a000000 0 0 000 0 0 0 0 0_ _ _ Y]a:@+-/a333^aY]aFI^`o(. ^`hH. pLp^p`LhH. @ @ ^@ `hH. ^`hH.
