An irregulаrly shаped sаmple оf a new material was fоund tо have a mass of 29.0 g. Because of the irregular shape, the displacement method was used to determine the volume of the sample. A 100. mL graduated cylinder was filled with water to the 50.00 mL line. When the sample object was placed in the cylinder, the water line rose to the 56.50 mL mark. What is the density of the new material (in g/cm3)?
