Calculation of mass

in maths •  6 years ago 

Molecular mass of elements

The mass of the sodium element (Na) can be calculated by finding it directly from the periodic table, which is equal to one mol of sodium, ie 22.99 g / mol. The molten mass of O2 can also be calculated by finding one mass of it, It is a two-valence molecule and its atomic weight is 16.00 g. The molar mass = 2 * 16.00 = 32.00 g / mol.
