Question

1) Calculate the absolute mass of an atom of oxygen. 2) Calculate the gram atomic of mass oxygen .3) Calculate the number of gram atomic mass of Sodium​

Answer 1

Explanation:

Correct option is

C

2.4×10−24g

The mass to charge ratio (m/e) for a cation is 1.5×10−8kg/C.

Charge on an electron = 1.6×10−19kg

Hence mass of the atom = 2.4×10−24g

Thus option C is correct
