Question

Cl, Br, I, if this is Dobereiner’s triad and the atomic masses of Cl and I are 35.5 and 127 respectively the atomic mass of Bris (A) 162.5 (B) 91.5 (C) 81.25 (D) 45.625

Tardigrade Admin · Accepted Answer

According to Dobereneir's triad the atomic mass of Br will be average of the atomic masses of Cl I =(35.5+127/2)=81.25

Q. $Cl, B r, I,$ if this is Dobereiner’s triad and the atomic masses of $Cl$ and $I$ are $35.5$ and $127$ respectively the atomic mass of Bris

162.5

91.5

81.25

45.625

According to Dobereneir's triad the atomic mass of $B r$ will be average of the atomic masses of $Cl$ & $I$
$= \frac{35.5 + 127}{2} = 81.25$
