Question

find the mass of 4*6.022×10^23 oxygen(atomic mass of oxygen=16)​

Answer 1

Answer:

The answer is 16.

Explanation:

The mass in grams of 6.022×10  

23

 atoms of oxygen is 16 grams. Because 6.022×10  

23

 is avagadro number. Avagadro number of particles are equals to the weight of its molecular weight. So atomic weight of 6.022×10  

23

 atoms of oxygen is  16 which is the atomic weight of oxygen.

Hope it helps .
