Question

what is mole concept and relative mass? How to find them

Answer 1

Answer:

it is defined as the ratio of the average mass of atoms of a chemical element in a in a given sample to the atomic mass constant

Answer 2

Relative mass :-

Relative atomic mass or atomic weight is a dimensionless physical quantity defined as the ratio of the average mass of atoms of a chemical element in a given sample to the atomic mass constant. The atomic mass constant is defined as being of the mass of a carbon-12 atom.

Mole Concept :-

The number of moles in a given sample of an element/compound can be calculated by dividing the total mass of the sample by the molar mass of the element/compound, as described by the following formula. Number ofMoles = (Mass of the Sample)/(Molar Mass)
