just substitute the atomic weights into the structures and work out values of n and m?
thanks
Atomic weights provide a way to compare the masses of different atoms, which is a crucial aspect of solving questions related to chemical reactions, atomic structure, and other scientific topics.
In order to balance a chemical equation, the number of atoms on the reactant side must be equal to the number of atoms on the product side. Atomic weights help determine the number of atoms in a given substance and ensure that the equation is balanced.
Atomic weight is the average mass of an element's atoms, taking into account the different isotopes and their relative abundance. Atomic mass, on the other hand, is the mass of a specific isotope of an element.
The atomic weight of an element can be calculated by multiplying the atomic mass of each isotope by its relative abundance, adding the results, and then dividing by 100. The resulting value is the atomic weight.
Atomic weights have decimal values because they are based on the average mass of all naturally occurring isotopes of an element, which may have slightly different masses due to the presence of different numbers of neutrons.
