Q:

How much does mercury weigh?

A:

Quick Answer

Mercury, the element, has a density of approximately 13.5 to 13.6 kg/m^3, and its overall mass depends on the volume collected. The planet Mercury has a mass of approximately 3.3 * 10^23 kilograms, or .055 times the mass of the Earth.

According to The Physics Hypertextbook, the element mercury has a density of approximately 13.594 kg/m^3. PeriodicTable.com reports a slightly different density of 13.534 g/cm^3. Given a certain volume of mercury, the mass can be found by multiplying its volume by the density of mercury. For example, the mass of 2 cubic meters of mercury is (2 m^3 * 13.594 kg/m^3) = 27.188 kg. Convert kilograms to pounds by multiplying the number of kilograms by 2.2046.

According to NASA, the planet Mercury has a mass of approximately 3.3010 * 10^23 kg.

  • Q:

    What happens when you split an atom?

    A:

    Also referred to as nuclear fission, splitting an atom results in its overall mass being reduced, causing the release of a relatively massive amount of energy. Virtually every atom can generate nuclear energy in this way, but those with the greatest atomic mass will provide the most energy from fission.

  • Q:

    When is an element chemically active?

    A:

    An element’s chemical activity is defined as its stability relative to the elements surrounding it on the periodic table. Chemical activity is also related to electronegativity. Elements that are highly electronegative are highly reactive, while elements that have low electronegativity are less reactive.
