Bir elementin atomlarının %92,21 inin kütlesi 27,97693 akb, %4,70 inin kütlesi 28,97649 akb ve %3,09 unun kütlesi 29,97376 akb ise elementin ortalama atom kütlesi nedir hesaplayınız? (

The average atomic mass of the element : 28.0856

The elements in nature have several types of isotopes  

Isotopes are elements that have the same Atomic Number (Proton)  

Atomic mass is the average atomic mass of all its isotopes  

Mass atom X = mass isotope 1 . % + mass isotope 2.% ..

Calculate the average atomic mass of the element if 92.21% of the atoms of an element have a mass of 27.97693 , 4.70% of a mass is 28.97649 , and 3.09% has a mass of 29.97376 ?

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
