Question

in a triad of a three elements A B and C the atomic masses of a is 75 and b is 125 find the atomic mass of elements c​

Answer 1

Answer:

75 u

Explanation:

We know that in a triad,

Arthimitic Mean of masses of extreme 2 elements = Mass of middle most element

(A+C)/2 = B

(75 + C) = 2*125 = 150

C = 150 - 75

C = 75 u

Answer 2

lets solve for it

Explanation:

In a triad, the elements are placed in such a way that if atomic masses of two elements are given then the atomic mass of the third element will be equal to the mean mass of the two elements.

(A+B)/2 = C

(75+125)/2  = C

200/2=C

100amu = C
