2) A sample of hydrated alum, KAl(SO4)2 . __H2O was analyzed by decomposition. a. Fill in the missing information in this list (show work below) Mass of beaker and watchglass: 95.886 g Mass of alum hydrate, beaker, and watchglass: 96.818g The of anhydrous alum, beaker, and watchglass: 96.393 g Mass of anhydrous compound Mass of water removed Moles of water removed Moles of anhydrous salt Formula of hydrate: KAl(SO4)2 . ____ H2O Mass % water Mass and moles of anhydrous compound: Mass and moles of water Mole ratio of water to anhydrous compound Mass % water

A solid hydrate weighing 2.691 g was heated to drive off water. A solid anhydrous residue remained, which weighed 2.259 g. calculate the percent of water in the hydrate. If anhydrous residue has a formula weight of 282 how many moles of water are present in one mole of anhydrous salt. What percent by weight of water is in the alum KAI(SO4)2·12H2O.
