A mole (mol). You can convert to kilograms using Avagadros number.
Scientists use atomic mass units (amu) or unified atomic mass units (u) to measure the mass of atoms and their subatomic particles. These units are based on the mass of a carbon-12 atom and are commonly used in the field of nuclear and particle physics.
Their mass is measured in atomic units 1 atomic unit is 1.660538782×10−27 kg A Proton has a mass of 1.007276466 u (u is the symbol for Atomic Mass) A Neutron has a mass of 1.008664915 u
You Use Atomic Mass Number
The atomic mass unit is 1/12 from the mass of the isotope 12C.
You would use kilograms (kg) to measure someone's mass in metric units.
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.
The international unit for mass is the kilogram.
Pounds
Atomic mass is so small you can't actually measure it. So, just like carbon dating, you have to use a relative mass.
When measuring mass, you need a unit of measurement, not a dimensionless number. In the case of an atom, you would use atomic mass units. Platinum weighs a lot more than 3.25 atomic mass units. It is a heavy metal.
No, millilitres is a measure of volume not mass. You would use milligrams.
Meters for height Kilograms for mass.
