An Atomic Mass unit is a unit that's used to measure the masses of atoms and molecules. Today, we use the unified Atomic Mass unit (u) which is 1/12 the mass of a carbon-12 nucleate that is unbound, at rest, and in it's ground state.
What else can I help you with?
How many atomic mass units are there in carbon-12?
12 by definition.
What is the AMU of carbon?
AMU stands for atomic mass units; the number of units an element has is called its atomic mass. The atomic mass of carbon is exactly 12, by definition.
What is the definition of 'Atomic Mass'?
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
What are the units in measurement for mass?
Mass units in the Metric system: Gram, kilogram Mass units in the English system: Poundal, Slug
What is the definition for mass?
Mass is a measure of the amount of matter in an object. It is a fundamental property of an object that determines its inertia and the force needed to accelerate it. Mass is typically measured in units such as kilograms or grams.
What is the density of a substance that has a mass of 36.9 and a volume of 3?
12.3 units of mass per unit of volume.12.3 units of mass per unit of volume.12.3 units of mass per unit of volume.12.3 units of mass per unit of volume.
What is the simplest definition of Equivalent Units?
in completed units converted into completed units
Which is heavier a centimeter or inch by how much?
Centimetres and inches are units of length, not mass. The units are not compatible with units of mass.
What will be the volume of a boy with a density of 15 and a mass of 20kg?
By definition: density = mass / volume Solving for volume: volume = mass / density Please note that a boy will NOT have a density of 15, at least, not if you use anything remotely related to SI units. The density of a person is close to that of water - with a density of 1, or 1000, depending on the units used.
What is the mass units for density?
Density is measured in units of mass divided by units of volume. The SI unit is kilograms/meter3.
What are the metric units of mass?
The metric units of mass are: Kilogram=mass of 4 videocassettes Gram=mass of a small paper clip Milligram=mass of an eyelash
What is a measure of the quantity of thr matter in the object?
The mass. Defining mass as "quantity of matter" is actually a rather informal definition. It helps a non-expert visualize the concept of mass, but it is not really a very precise definition. Mass can better be defined by its inertial (the way it reacts to acceleration), or by its gravitational interaction.The mass.
