My compound is MgSO4 bonded to 7H2O
1) Based on the molar mass of anhydrous salt (1.25) calculate the moles of anhydrous salt. determine the smallest whole number ratio of moles of water to moles of anhydrous salt.
2) Determine the empirical formula for your compound (use moleratio)
3) What is the percent water in your hydrate? what is the percent error for this investigation?
4) Predict what would happen if you added a few drops ofdistilled water to the anhydrous salt remaining at the end of this experiment?
