%H2O for Li(OH)2.H2O = (18/60)*100 = ?
Find %H2O in all of them, the ones with the most percent water will lose the most mass for a 1.0 g sample.
If 1.0 g samples of each compound were
dehydrated, which sample would lose the greatest
mass of water?
Molar Masses:
LiCl* H2O= 60. g mol–1
MgSO4* H2O= 138. g mol–1
FeSO4*H2O= 170. g mol–1
SrC2O4*H2O=194. g mol–1
