Bill finds an unusual object and wishes to calculate it's density. He discovers a problem of accurately weighing it, because it won't stay on the weighing pan. To solve this he adds the object to a beaker containing 178 mL of distilled water and finds the water level rises to 270 mL. The flask of water weighed 826.5 grams after the object was added. If the empty beaker weighed 479 grams, calculate the following:
