Question

Three elements X, Y, Z are components of Dobereiner's triads. If atomic masses of X and Z are
32 and 128 respectively then what will be the atomic mass of element Y?

Answer 1

Answer:

80

Explanation:

X,Y,Z are in dobereiner's triad,

Atomic mass of Y = X + Z/2

= 32+128/2

= 160/2

= 80
