please help with these problems. Much appreciated. Thank you
4. You are given an unknown hydrated metal salt containing chloride ion, MCl, nH,O. You dissolve 0.500 g of this salt in water and add excess silver nitrate solution, AgNO, to precipitate the chloride ion as insoluble silver chloride, AgCI. After ound to weigh 0.720g a. What is the mass percent chloride in the metal salt? b. A second 0.500 g sample is dehydrated to remove water of hydration. After drying, the sample is found to weigh 0.319 g. What is the mass percent water in the metal salt? The metal cation has a charge of two. What is the molar mass of the metal? What is the identity of the metal? c. d. Determine the complete empirical formula of the hydrated metal salt.
