Question

Atomic weight of Barium is -------- if Calcium’s is 40 and Strontium’s 87.5 according to triad.

Answer 1

Answer:

If Barium is the middle element in the triad,

The atomic weight must be = Taking the weight as x.

= (x+40+87.5)/3 = x

= x+40+87.5 = 3x

= 127.5 = 2x

= 63.75 g = x

This is atomic weight of Barium (only if it is the middle element in the triad). However, it can an approx. value too.

Hope this helps.
