A 200-gram aqueous solution of NaCl (58.45 g/mol) was found to contain 0.5 mole NaCl for every 1 kg of H20. If another 500-gram solution was added containing 0.01 mole NaCl for every 1 kg H2O was added to form a dilute solution, calculate the following: (express all answers in four decimal places) (a) mass (grams) of NaCl in the 200-gram solution (b) mole of NaCl / kg water of the resulting dilute solution (c) % mol H2O in the resulting dilute solution
