How to calculate the relative atomic mass of an element?

The relative atomic mass of an element is the sum of the atomic masses of all of the isotope of that element. In other words, the relative atomic mass of an element is the sum of the atomic masses of all the isotopes of that element that are known to exist. The atomic mass of an isotope is given in atomic mass units, or amus.

How to calculate the relative atomic mass of a compound?

For a pure solid, the relative atomic mass is simply the atomic weight of its chemical formula's atoms as a whole. This includes the weight of any atoms that are part of the structure but do not contribute to a compound's chemical properties. So, think of the sum of the relative atomic masses of all the elements in a chemical formulálum as the total mass of the chemical.

How to calculate the relative atomic mass of a molecule?

The relative atomic mass of an element or a molecule is the ratio of the mass of the element or molecule to the sum of the isotopes’ masses. The sum of the isotopes’ masses includes the sum of the atomic masses of all the atoms of the element or molecule. Hence, the relative atomic mass is the mass of the element or molecule divided by the sum of the isotopes’ masses.

How to calculate the relative atomic mass of water?

The relative atomic mass of water is relative to the relative atomic mass of hydrogen. This is because when two atoms combine, the sum of their relative atomic masses is conserved—this is known as the law of conservation of mass. The relative atomic mass of hydrogen is 1.0079, so when two hydrogen atoms combine, they form one molecule of water with a relative atomic mass of 18.0153.

How to calculate the relative atomic mass of a chemical?

The relative atomic mass is a ratio of the mass of one atom’s nucleus (or nuclei, for a chemical) to the sum of the masses of its atoms’ nuclei. This is a good measure of the chemical’s stability, as the more stable a chemical is, the fewer lighter atoms it will need to be to stabilise it.
