In lab, an empty weigh boat measures 11.7 g. A piece of metal is added to the weigh boat, and the total mass increases to 19.5 g. A graduated cylinder is filled with 24.2 mL of water. The piece of metal is carefully added to the graduated cylinder, and the volume increases to 28.0 mL. Using this data, find the density of the piece of metal, in units of g/ml. Do not include units in your answer.
