Molecular weight of oxygen is 32g that is 1 molecule of oxygen is_(64,16,32) times as heavy as 1/12th the mass of carbon atom.

Explanation:

Atom

  1. It  is a smallest particle of an element which may as may not have independent existence.  
  2. The are very small in size.  
  3. Their size is measured in unit nm
  4. 1nm = 10⁻⁹ m.  
  5. Hydrogen atom is smallest of all size is only 10⁻¹⁰ nm  
  6. We cant calculate their absolute mass , but yes we can calculate its relative mass .
  7. But for that standard element is to fixed.That standard element is : C-12

Atomic mass of element-  

Active atomic mass of atom can’t be measured but relative atomic mass can be known.  

I.e.  relative atomic mass of an atom of element is defined as average relative mass of atom as compared with atom of Carbon atom  taken as 12u.

Atomic mass

Its is the number of times an one atom of he element is heavier then 1/12th of C atom.  

Molecule

It is smallest particle of an element or compound which is able to exist independently.  

Molecular mass : It is the mass of molecule .

Like , an atom has atomic mass .Similarly, molecule has molecular mass .

Oxygen : has atomic mass 8 therefore ,for oxygen molecule it will be 32g .

This statement means that oxygen molecule is 32 times heavier than 1/12 of mass of carbon atom .
