The atomic mass of oxygen is 16.

As One molecule oxygen consists of 2 atoms of hydrogen,
One molecule of oxygen is 32 times heavier than the hydrogen atom.
So, the correct answer is D.

2 atoms makes 1molecule of oxygen= 2*16 = 32.
Here hydrogen atom is not molecule = 1
So, answer D is correct which 32 times is heavier

The answer should be 16 because the molecular mass of hydrogen is equal to 2 and the molecular mass of oxygen is 32.

The molar mass of oxygen is about 16 g/mol. So a mole of O2 weights approximately 32 g/mol.

Molecular mass of oxygen is 16 and that of hydrogen is 1. So answer is 16.

It is correct an atom of hydrogen is 1 while a molecule of oxygen is 32.

Shrikant said:   9 years ago
Molecular weight of hydrogen is 1.

And molecular weight of oxy is 16.

The answer is wrong.

I molecule 9f o2 is 16 times heavier of h2.

Anoms said:   8 years ago
I think answer is correct because;

O2 16*2=32.
H =1..
So 32.
(2)
