Finding Density Experimentally

How could density be determined experimentally? Is this an intensive of extensive property?

Density=\mathrm{\dfrac{mass}{volume}}

Liquid: mass container

    • add a known volume of liquid
    • mass container +liquid – container
    • mass of liquid
    • volume of liquid = density for liquid

Solid: mass solid alone

    • add solid to water bath
    • measure water displaced
    • calculate the volume displaced of a geometric shape
    • \mathrm{\dfrac{mass\quad of\quad solid}{volume\quad of\quad solid} = density\quad of\quad solid}

Intensive = not changing with the amount of substance, molecular weight, color, or chemical make.

Extensive = can change with the amount of substance, mass, volume, or moles

Density doesn’t with the amount of substance therefore density is intensive.
