Balancing a Chemical Equation

Balancing a Chemical Equation The number of atoms on each side of a chemical equation must be equal. To balance a chemical equation the following rules must be followed: –After you have written a chemical equation check to see if the equation is balanced (have the same number of atoms of each element on each…

Relative Atomic Mass and Relative Molecular Mass

Relative Atomic Mass and Relative Molecular Mass Relative Atomic Mass As you can imagine the mass of an atom would be significantly small. It is for this reason that we do not use the actual mass of an atom in calculations, instead we use the Relative Atomic Mass (R.A.M). RAM is the mass of an…

The mole

The mole The mole is a common unit used to represent the quantity of a chemical substance and is the amount of that substance that contains 6.2023×1023 particles (Avogadro’s constant). Number of moles =mass of substance/R.F.M Calculating masses Na2SiO3 R.F.M= (R.A.M Sodium x 2) + (R.A.M Silicon) + (R.A.M Oxygen x 2) R.F.M= (23×2)…
