Table 2: Magnesium Chloride Measurements mass of empty crucible (g) 35.000g mass of crucible and magnesium chloride hydrate 40.000g (g) - before heating 37.342g mass of crucible and magnesium chloride anhydrous salt (g) - after heating Mass of magnesium chloride anhydrous salt (g) 2.342g (mass of crucible and magnesium chloride anhydrous - mass of empty crucible) Mass of water in hydrate (Mass of water removed) (g) (mass of crucible and magnesium chloride hydrate - mass of crucible and magnesium chloride anhydrous salt) Number of moles of magnesium chloride anhydrous salt (mol) number of moles of water (mol) molar ratio of anhydrous salt to water formula of the magnesium chloride hydrate (40.000g)-(37.342g)= 2.658 g 0.0246 mol 0.1475 mol 0.0246: 0.1475-1: 5.996 =1:6 MgC12*3H2O

Calculations: The molar mass of water is 18.015 g/mol and the molar mass of anhydrous magnesium chloride is 95.211 g/mol. Show your calculations - they will be similar to the calculation method used for copper sulfate hydrate. Value of n moles determined = 0.033 mol Formula of compound = MgC12*3H2O Name of compound = __
