Relative Formula Masses

Calculate the relative formula masses of individual chemical species and apply this within the context of balanced chemical equations.

Calculate the specific percentage by mass of a given element within a compound using its relative formula mass and relative atomic masses.

Understand that the relative atomic mass of an element is an average value representing all its isotopes, compared directly with the Carbon-12 isotope.

Calculate the relative formula mass of a compound by summing the relative atomic masses of all atoms indicated in its chemical formula.

Prove that, in a correctly balanced chemical equation, the total sum of the relative formula masses of the reactants equals the total sum for the products.

Carry out mathematical and statistical analyses related to relative formula mass without the need to calculate atomic masses from isotopic abundances.
