Oxygen has an atomic number of 8. What is the approximate atomic mass of an oxygen atom in daltons (Da)?

Answer : The approximate atomic mass of an oxygen atom daltons (Da) is, 16 Da

Explanation :

As we know that dalton (Da) is equal to atomic mass unit (amu).

As we are given that,

Element = oxygen

Atomic number of oxygen = 8

As we know that the atomic mass of oxygen = 16 amu

So, the approximate atomic mass of an oxygen atom in daltons (Da) = Atomic mass unit of oxygen = 16 amu = 16 Da

Thus, the approximate atomic mass of an oxygen atom daltons (Da) is, 16 Da
