`3.011 xx 10^22` atoms of an element weighs `1.15 gm`. The atomic mass of the element is :

Define atomic mass of an element.

An element E crystallizes in boyd centred cubic structure. If the edge lengh of the cell is 1.469xx10^-10m and the denstiy is 19.3 g cm^-3 , calculate the atomic mass of this element. Also calculate the radius of an atom of the element.

The atomic mass of an element is the weighted average of the atomic masses of different isotopes of that element .This explains,why atomic masses of many elements show large departures from integer values.However ,even if we consider msases of individual isotpes,they are not strictly integer multiples of the mass of a hydroen atom.How do yo account for this fact?

An element crystallising in body centred cubic lattice has an edge length of 500 pm. If its density is 4gcm^-3 , the atomic mass of the element is

One atom of an element x weighs 6.643 xx 10^(-23)g . Number of moles of atoms in its 20kg is :

An element with density 10 g cm^(-3) forms a cubic unit cell with edge length of 3xx10^(-8) cm.What is the nature of the cubic unit cell if the atomic mass of the element is 81 g mol^(-1)

What is obtained when the atoms of the same element combine ?

Isotope of which element is used in atomic reactor?
