Question

One atom of an element weighs 1.8 * 10 -22 g . what is the atomic mass of element ?

Answer 1

if we take Avogadro Number as 6x10^23 then atomic mass of the element will be 108amu

Answer 2

Answer: Thus the atomic mass of the element is 108.4 g.

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to the atomic mass and contains avogadro's number $6.023\times 10^{23}$ of particles

Given : One atom of an element weighs $1.8\times 10^{-22}g$

Thus if 1 atom weighs =  $1.8\times 10^{-22}g$

$6.023\times 10^{23}$ atoms will weigh=$\frac{1.8\times 10^{-22}}{1}\times 6.023\times 10^{23}=108.4g$
