expressed in unified atomic mass unit, amuHowever, for practical purposes in the laboratory the relative atomic mass is used so the unit would be gram. (Relative atomic mass compares the mass of all elements to that of the carbon-12 isotope taken as exactly 12)
An elements density is its mass per unit volume. It is also how packed together the molecules are in the element. For example, a rock is more dense then a piece of paper. Well if you were to relate that to elements, you could say Hydrogen is less dense then Gold. The formula is density=mass/volume
The SI unit for mass is kilogram. Mass is not a unit.
There are seven base units in the SI - System International, of which Mass is one, and the kilogram is the base unit. (Weight is mass x acceleration.)At this moment, the unit of mass is referred to a prototype standard kilogram - a physical piece of metal.It is intended to re-define the unit of mass in terms of the mass of some fundamental particle, and this will be related to mass by the use of Avagadros number, or Planck Constant. Possibly using an ultra-precision sphere of high purity silicon.
The SI unit of mass is the kilogram.
Mass of a substance is usually measured in standard unit called kilogram (kg) . Hence unit of mass of a piece of pad paper will be in kg.
the unit is pop. = Piece Of Paper
probably a meter!

Grams
grams
It is measured in grams.
There's no "correct" unit. You can use any unit of mass you like, althoughthe gram is sure to result in the most convenient final number.

The metric unit of mass is kilogram. It is the mass of a piece of platinum alloy that keep in a museum in Paris. One kg (kilogram) is equal to 1000 g (gram). One kg (mass) weighs 2.205 pounds on the surface of the Earth.
