The formula weight of an element (or a compound or a species) is the sum of the weights of the atoms making up its chemical formula. The formula weight of an element is its atomic weight and that of a compound is its molecular weight. The equivalent weight of an ion is the ratio of...

Atomic weight, molecular weight, and molar mass Example: Calculating sulfur’s atomic weight Molecular weight and atomic weight Limitations of the mole Thisover defining thecan seem a little strange. After all, the mole is not a term we need to refer to most things in daily life (such as ...
The term "atomic weight" consists of the word "atom" which allows one to infer that the term is related to atoms. Atoms are molecules that consists of subatomic particles: electrons, neutrons and protons:Answer and Explanation: Atomic weight- also known as atomic mass- refers to the ...
The atomic mass of an element (or atomic weight) M is defined as the average of the isotopic masses, i.e. Mi is weighted by the atomic fraction xi of its isotope: (2.4)M=x1M1+x2M2+…=∑xiMi As an example, natural chlorine consists of two isotopes of which one has an abundance of...
atomic weightof an element is its mass relative to carbon-12 having a mass of exactly 12; atomic weight is also dimensionless. The terms ‘molecular weight’ and ‘atomic weight’ are frequently used by engineers and chemists instead of the more correct terms, ‘relative molecular mass’ and ...

(in inorganic chemistry) and many molecular and atomic weights could be measured directly. The drawback to hydrogen as a reference was that it combined directly with a limited number of elements only and the atomic weight must be evaluated in comparison with oxygen. As the oxygen to hydrogen ...
Weight Versus Mass: Atoms and More Massis a measure of the quantity of a substance, whileweightis a measure of how a mass acts in a gravitational field. On Earth, where we are exposed to a fairly constant acceleration due to gravity, we don't pay much attention to the difference between...
