X,Y and Z are three members of a Doboreiner's triad . If the atomic mass of X is 7 and that of Z is 39 , what in the atomic mass of Y?

Text Solution

Verified by Experts

Atomic mass of X = 7
Atomic mass of Z = 39
`:. ` According to Dobereiner.s Triad, atomic mass of Y
`=(X+Z)/2=(7 + 39)/2=46/2 =23`
`:.` Atomic mass of Y = 23
