A student places 10.3 mL of water in a graduated cylinder. The mass of the water and the graduated cylinder is found to be 42.020 grams, and then the balance is tared. After adding a number of metal pellets to the graduated cylinder, the liquid level in the cylinder is now 26.1 mL. The cylinder with the water and metal pellets is placed back on the balance, and the measured mass is 55.782 grams. Calculate the density of the metal pellets in g/mL. Do not include units in your answer.
