* Atomic volume = Atomic weight ÷Specific Gravity. By atomic volume is meant the volume in cubic centimeters which a combining weight in grammes of the element occupies. In textbooks and papers, the density is usually given instead of the specific volume, which is its reciprocal, i.e. to find the atomic volume, the atomic weight is divided by the density.

GHS Symbols and Labelling

The globally harmonised system of classification and labelling of chemicals.

This GHS deals with the classification of chemicals by types of hazard and provides harmonized elements that communicate these hazards, including labels and safety data sheets.

New GHS pictograms are replacing the traditional orange symbols.  You may have already seen these on chemical pacakaging.

Please download the useful poster below for more information.
