define the following
a.Atomic mass
Answers
Answer:
the mass of an atom of a particular chemical substance.
Oxygen has an atomic mass of 16.
The atomic mass is the mass of an atom. Although the SI unit of mass is the kilogram, atomic mass is often expressed in the non-SI unit dalton where 1 dalton is defined as 1⁄12 of the mass of a single carbon-12 atom, at rest. Wikipedia
Symbol
This was adopted as the 'unified atomic mass unit'. The current International System of Units (SI) primary recommendation for the name of this unit is the dalton and symbol 'Da'. The name 'unified atomic mass unit' and symbol 'u' are recognized names and symbols for the same unit.

Hint: Atomic mass is the mass of one atom of a given element. Unified atomic mass unit is the unit of the atomic mass and is given the symbol 'u'. ... Hence, you can say that the atomic mass is equal to the total mass of all the protons and neutrons present in the nucleus of an atom.
Answer:
Atomic mass
tomic massAtomic mass refers to the mass of an atom. It depicts how many times an atom of an element is heavier than one-twelth (1/12th) the mass of one atom of carbon-12 of mass of one carbon atom. The relative atomic masses of all elements have been established with reverence to an atom of carbon-12. It is measured in unit called amu (atomic mass unit). 1/12 of the mass of one atom of carbon is termed as relative atomic mass. It doesnot possess a unit.
Explanation:
mass of one atom of an element = atomic mass X (1/12th) of the mass of one atom of carbon.
mass of one atom of an element = atomic mass X (1/12th) of the mass of one atom of carbon. Or
mass of one atom of an element = atomic mass X (1/12th) of the mass of one atom of carbon. Oratomic mass = mass of one atom of an element / (1/12th) of the mass of one atom of carbon.
mass of one atom of an element = atomic mass X (1/12th) of the mass of one atom of carbon. Oratomic mass = mass of one atom of an element / (1/12th) of the mass of one atom of carbon.
mass of one atom of an element = atomic mass X (1/12th) of the mass of one atom of carbon. Oratomic mass = mass of one atom of an element / (1/12th) of the mass of one atom of carbon.
mass of one atom of an element = atomic mass X (1/12th) of the mass of one atom of carbon. Oratomic mass = mass of one atom of an element / (1/12th) of the mass of one atom of carbon. Easy way to calculate atomic mass of oxygen atom.
