Question

The atomic mass of oxygen is 16u.

Considering the above statement, which among the following options can be inferred?

• A. The mass is with respect to Carbon -12 atom.
• B. The atomic mass of Oxygen is 16 of the mass of carbon 12 atom.
• C. The atomic mass of hydrogen is 16 times the mass of Hydrogen.
• D. The mass is with respect to Carbon -12 atom and the atomic mass of Oxygen is 16 of the mass of carbon 12 atom.

Answer 1

The correct option is D

The mass is with respect to Carbon -12 atom and the atomic mass of Oxygen is 16 of the mass of carbon 12 atom.

The relative atomic masses of all elements are found with respect to carbon-12 atom.

One atomic mass unit is ${\frac{1}{12}}^{th}$ of the mass of one atom of carbon-12.

The atomic mass of oxygen is 16u represents that atomic mass of oxygen is $16$$\times$$\frac{1}{12}$ of the mass of carbon-12 atom.
