How can you determine the atomic mass of an unknown metal if you know its density and the dimension of its unit cell ? Explain. |
|
Answer» Solution :Atomic MASS is related to DENSITY of the solid d, edge length a, number of particles in a unit cell Z by the following equation : Atomic mass, `M=(d"xxa^(3)xxN_(A))/(z)` where `N_(A)` stands for Avogadro.s number `6.022 xx 10^(23)`. By substituting the values of VARIOUS quantities, we can DETERMINE the atomic mass of the element. |
