Question

The charge by mass ratio of an ion M* is
4.2 x 106 C kg-9. The ion is
(a) Ag*
(b) Cu*
(c) Cs*
(d) Na*​

Answer 1

Answer:

Mass/Charge of A+= (1.97x10-7kg/charge)

Charge of an electron= 1.6 x 10-19

Thus Mass of 'A' atom = (1.6 x 10-19)(1.97x10-7)= 3.16 x10-26Kg

Explanation:

d is correct
