For these reasons the number 16 has been chosen as the atomic weight of oxygen.
These, then, are the steps necessary to establish the atomic weight of an element.
From the following data calculate the atomic weight of sulphur.
The smallest number so obtained will be approximately the atomic weight.
We see, therefore, that the atomic weight is twice the equivalent, or 55.9.
The atomic weight of manganese has been frequently determined.
These are the signs for the atomic weight of lead, and of silicium.
According to Zschiesche the atomic weight of lanthanium is 9018.
This would give for the final product an atomic weight of 206.
The other element, to which he gives the name Nebulium, will have an atomic weight of 2·1.
