Unformatted text preview: Volume of Liquid = mass/density = .5260 g .672 mL = .783 g/mL Volume of Solid = 1.00 mL - .783 g/mL = .217 mL Density of Solid = .369 g .217 mL = 1.70 g/mL Melting Point 1. I ran out of time before I could find a rough melting point. 2. exact --- 1 st time turns to liquid = 52 C--- all is liquid = 62 C...
