Unformatted text preview: anhydrous salt, determine the mass of the water that was driven off. From the empirical formula of the anhydrous salt provided by your lab instructor, determine the molecular mass of the anhydrous salt. From the molecular mass of this salt and the mass of the anhydrous salt, determine the moles of anhydrous salt. Similarly, determine the moles of the water. Divide the moles of water by the moles of anhydrous salt; from this, determine the empirical formula....
