###### Supposc that a 2.750 g sample of chromium chloride hydrate, CrCb xHzO,is completely dehydrated by heating The recovered anhydous procct, CCb, wcighs 1.631 g Follow Ihe stcps taken in loday' 5 experient and determine the number of watcr molecules in Ihc formula of the hydratechemical reagent bollle, poorly labeled as iron chloride hycrate , is discovered i the stockroom It is most likely either FeClz-6HzO or FeCh 4HzO A dehydation expcriment reveals that the hycrale is 36 22%

Supposc that a 2.750 g sample of chromium chloride hydrate, CrCb xHzO,is completely dehydrated by heating The recovered anhydous procct, CCb, wcighs 1.631 g Follow Ihe stcps taken in loday' 5 experient and determine the number of watcr molecules in Ihc formula of the hydrate chemical reagent bollle, poorly labeled as iron chloride hycrate , is discovered i the stockroom It is most likely either FeClz-6HzO or FeCh 4HzO A dehydation expcriment reveals that the hycrale is 36 22% water by mass Which of the two possible hydrate salts is it? A hydrate of zirconium(I) nitrate, ZI(NO3)z HzO was found to be 29.50% water bv mass What is the forula of this hydrate? Hint_ percent is parts-per-hundred Suppose that you start with a 100 g sample ofthe hydrate: What would be the mass of water and the mass of anhydrous Zr(NO3)2?
