An empty 25.00 mL volumetric flask has a mass of 20.550 g. When it is partially filled with metal pellets, the mass is 130.278 g. The flask is then filled to the mark with methanol (density = 0.7918 g/mL), and the total mass of the flask, metal, and methanol is 142.419 g. Calculate the density of the metal pellets

    Density is a value for mass, such as kg, divided by a value for volume, such as m^3. Density is a physical property of a substance that represents the mass of that substance per unit volume. We calculate as follows:

    Density = (130.278 - 20.550) / (142.419 - 130.278) / 0.7918 = 7.16 g/mL
