| December 18, 2020 | education
Na2SO4. Let’s see what this substance consists of:
Two sodium atoms: 2 * 23 = 46 g / mol
One sulfur atom: 1 * 12 = 12g / mol
Four oxygen atoms: 4 * 16 = 64 g / mol
Let’s summarize:
64 + 46 + 12 = 112 g / mol
If that 23,12 and 16 – the relative atomic mass of the elements according to the periodic table
