Density of Irregular Solid #1 The change in the volume of water in a graduated cylinder is equal to the volume of an solid that has been completely submerged in the water. This method of determining the volume of a solid is said to be done by “H2O Displacement”. Measure the mass of one of the small irregular solids with a triple beam balance. Fill a 100-mL graduated cylinder with enough water to completely submerge the solid. Record this volume of water as “Volume Before”. Hold the cylinder at an angle and slowly slide the irregular solid into the water. Record the new volume of water as “Volume After”. Calculate the volume and density of the irregular solid. Mass (g)

Density of Irregular Solid #2 Measure the mass of one of the larger irregular solids with a triple beam balance. Use the water displacement technique to determine the volume of the solid in a 500-mL or 1000-mL graduated cylinder. Calculate the volume and density of the irregular solid. Clean up your lab station and return to your desk. Mass (g)
