Atomic mass
Question:
1
m.
Identify the correct answer:
Akash says, “Atomic mass unit is \(1/16\) of the mass of an oxygen atom.” How would you guide them based on modern IUPAC standards?
The unit depends on the element being measured
They are correct; this is the global standard
That was used earlier, but now \(1 u = 1/12\) of a carbon - \(12\) atom
It’s still based on oxygen in advanced research
