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
