Data and Results Use the table below to record your data and results al 1 al 2 al 3 Mass of aluminum dish (g) Mass of aluminum dish and Epsom Salt (g) Epsom salt, original mass of hydrated salt (g) Mass of aluminum dish Epsom salt after heating(g) Mass of anhydrous salt (g) Mass of water (g) Moles of magnesium sulfate (mol) Moles of water (mol) Ratio of water to anhydrous salt (Round to the nearest whole number.) 1.5 1.47 0.21 1.41 1.62 1.41 18.0 78 1.27 1.51 0.24 1.49 X1.73 X1.49 X18.0 X83 × 1.2 1.48 0.23 1.45 1.68 X1.45 X18.0 × 80 1.7 Type the formula for Epsom salt based on your results.Use an average chemPad Help Greek MgSO4 7 H20 MgSO 4.7 H 20 Your answer contains an incorrect solvate ratio. Look up the actual formula of the Epsom salt hydrate and enter below Help chemPad Greek MgSO4 7H20 MgSO_4. 7H 20 Your answer appears to be missing a solvate dotExplanation / Answer
Formula of hydrated epsom salt
Trial 1 Trial 1 Trial 1
mass of anhydrous salt (g) 0.15 0.22 0.20
mass of water (g) 0.06 0.02 0.03
moles MgSO4 (mmol) 1.24 1.83 1.67
moles water (mmol) 3.33 1.11 1.67
ratio (water/anhydrous salt) 3.00 2.00 1.00
Formula of epsom salt = MgSO4.2H2O
[formulas, mass of anhydrous salt = mass of original salt + aluminium dish - mass of salt after heating + aluminium dish
moles anhydrous salt = mass anhydrous salt/molar mass MgSO4 (120.4 g/mol)
mass water = mass hydrate salt - mass anhydrous salt
moles water = mass water/molar mass H2O (18 g/mol)]
