WebThe atomic mass unit (u or amu) is a relative unit based on a carbon-12 atom with six protons and six neutrons, which is assigned an exact value of 12 amu's (u's). This is the standard unit for atomic or molecular mass, and 1 amu is thus 1/12 th the mass of a 12 C atom. This is obviously very small. 1 amu = 1.66054x10-27Kg = 1.66054x10-24 g.

WebThe formula mass of each reactant or product can be used to calculate the reacting masses. Example Calculate the mass of aluminium formed when 51 g of aluminium oxide are electrolysed. WebOxygen is a chemical element with atomic number 8 which means there are 8 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs.
