Question

how to find atomic mass of an element? expalin with examples

Answer 1

Heyya frnd..
__________

THE ATOMIC MASS WE CAN FIND IN ACORdING TO PERIODIC TEBLE..

ATOMIC MASS is MEASURED BY ITS SIZE.

SO THE

Atomic masses are often listed as decimal values ​​in the periodic table, usually under the element symbol or name. These numbers require a unit of mass connected with them. Atomic masses are usually given at atomic mass units, or amu, where

1 AM = 1/12 mass of a carbon-12 atom

Dalton is a common unit of amu; a Dalton = 1 AMU; these two units can be used alternately. Ami unit is not often used in chemistry.
Instead the atomic mass is equal to the number grams of the element in one mole of atoms of the element.The units of measurement for this is grams/mole, or simply g/mol.

example...

FIRST THING WE KNOWN THE element symbol OF THAT ELEMENT LIKE WE FIND THE ATOMIC MASS IN NITROGEN..

SO THE ELEMENT symbol is N

and NO. OF THE NITROGEN in periodic table is .. 7..

Using this periodic table, we see the atomic mass of nitrogen is 14.01 amu or 14.01 g/mol.

thank you
