N, P and As have similar properties. Check whether the average of atomic masses of N(14) and As(74.9) is equal to the atomic mass of P(31). Could we call it as a Dobereiner triad? Why? Give reason, plz dont spam

Answer:

We assume that N, P, As follow the Dobereiner's triads. It follows that M(P)=  

2

(M(N)+M(As))

​  

 

M(P)=  

2

(14+74.9)

​  

=44.45

Absolute error in mass of phosphorous =44.45−31=13.45
