Zak Barger 1/14/03 Chem. Lab Hydrated Compound Lab 1/ /03 Purpose The purpose of this lab was to find the mole ratio of water to anhydrous salt in the hydrated compound, which was given to us. By using a Bunsen burner and other materials, my group witnessed the evaporation and change that took place with the hydrated compound. Materials Evaporating dish, Bunsen burner apparatus, crucible tongs, hydrated compound Pre-lab Calculations> Molar mass of anhydrous sulfanilic acid = 172 g/mol> Mass of water = 18 g> Mass percent of water in the hydrated sulfanilic acid = .3139> 31%> Ratio of moles of water to moles of anhydrous sulfanilic acid = 30/170 g/mol> Empirical formula of hydrated sulfanilic acid = N6 H12 C36 H29 S6 O18 Data> Mass of the hydrated compound = 30.0 g> Mass of anhydrous compound => Mass of water driven off = 27.2g> Molar mass of the anhydrous compound...
