Answer:

Assume, At. Mass of Metal be ‘M’ and Oxygen be ‘O’

then,

Molecular Mass of metal oxide = 2 * M + 3 * O = 2M + 48

According to question,

68.4 %of mass of Metal Oxide is equal to Mass of Oxygen in it

68.4 %

of (2M + 48) = 48

or, 2M + 48 = 48* (100/68.4)

or, 2M = (4000/57) - 48

or, M = 1264/(57*2) = 11.08

therfore by solving you get, Atomic Mass of the Metal as 11.08 amu
