Question

2. Define atomic mass unit (amu). Calculate mass of one oxygen atom in terms of amu. (Avogadros
No. -2.656 X 10-23)​

Answer 1

Answer:

HOPE IT HEPLS

Explanation:

ATOMIC MASS UNIT : ONE ATOMIC MASS UNIT IS EQUAL TO EXACTLY ONE-TWELTH (1/12TH) THE MASS OF ONE ATOM OF CARBON -12 IS CALLED ONE ATOMIC MASS UNIT ( AMU) . IT IS WRITTEN AS ' u' .

Oxygen's atomic weight is 16.00 amu.

1 mole of oxygen is 6.02 x 1023 atoms of oxygen

1 amu = 1.661 x 10-24g
