8 vanderwaals radius. Use this periodic table for calculating molar mass for any chemical formula. Options for hiding the symbol or name of the elements provide a handy learning aid for memorizing the periodic table.
Ios app is also available. Interactive periodic table with up to date element property data collected from authoritative sources. Look up chemical element names symbols atomic masses and other properties visualize trends or even test your elements knowledge by playing a periodic table game.
For example carbon had an atomic weight of 12 00 in 1902 but today it is. For each element the atomic weight is on the periodic table right under the symbol of the element. The carbon atomic weight is 12 units of atomic mass amu so the weight of one mole is 12 grams.
A sample consisting the atoms of a single element weights the sample in grams and separates the element by its atomic weight. The molar mass of a known substance is easily obtained from its chemical formula using relative atomic mass data listed routinely in a periodic table of chemical elements. The procedure is similar to obtaining values for relative molecular mass that you may already have carried out.
Molecular weight number of carbon atoms c atomic weight number of h atoms h atomic weight so we calculate as follows. Molecular weight 6 x 12 01 14 x 1 01 molecular weight of hexane 72 06 14 14. Periodic table of the elements pte combined with information about elements and calculation of molecular formulas and their molecular weight also named molar mass the amount of the contained elements in percent is given.
