An atomic mass unit (amu) is a unit of mass used to express atomic and molecular weights. It is defined as a twelfth of the mass of an atom of carbon-12. Since atoms have very small masses, the amu is used to provide a more practical and meaningful scale for representing these minuscule values.
The small piece of aluminum will have greater density than the large piece of aluminum. Density is mass divided by volume, so for the same material, a smaller piece will have more mass per unit volume compared to a larger piece.
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
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)
You would typically use grams (g) or milligrams (mg) to measure the mass of a paper clip.
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!

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.
