what is the value of atomic mass number in gram and Kilogram
Answers
Answer:
Atomic mass of an element can be defined as the number which indicates how many times the mass of ... 1.66 x 10 -27 Kg. ... Hence, Gram atomic weight of oxygen = 16 gm .
Answer:
Atomic mass-
” Atomic mass of an element can be defined as the number which indicates how many times the mass of one atom of the element is heavier in comparison to 1/12th part of the mass of one atom of carbon-12.”
Atomic mass unit-
It is represented by ‘amu’. It is equal to the quantity 1/12th mass of an atom of C-12.
Average Atomic weight (Mass)-
“The Average Atomic Masses of many elements are determined by multiplying the atomic mass of each isotope by its fractional abundance and adding these values and then dividing it by 100.
Gram atomic mass(weight) or gram atom –
“Gram atomic mass(weight) of an element is the mass of Avogadro number ( 6.023 x 1023 ) of atoms of that elements in grams.”
Ex –
No. of gram atoms = mass of element in gm / atomic mass of element in gm.
