For example, sulfur is commonly known to have a standard atomic weight of 32.065. However, its actual atomic weight can be anywhere between 32.059 and 32.076, depending on where the element is found.
So, what they’re saying is, the atomic weight of sulfir will STILL be “commonly known” as being pretty damned close to 32.065.
No, the atomic weight for sulfur still be “commonly known” 32 no one cares past that.
Good point.
