Step 1: Calculate the volume of the solid. The volume of the irregular solid is determined by the displacement of water. Given initial water level = 20\, mL and final water level = 50\, mL. Volume of solid = Final water level - Initial water level Volume of solid = 50\, mL - 20\, mL Volume of solid = 30\, mL Step 2: Calculate the density of the solid. The density is given by the formula Density = MassVolume. Given mass of solid = 78.4\, g and calculated volume of solid = 30\, mL. Density = 78.4\, g30\, mL Density = 2.6133...\,g/mL Density ≈ 2.61\, g/mL The density of the irregular solid is 2.61 g/mL. That's 2 down. 3 left today — send the next one.
