Question

in a triad of 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:

average of A and C=B

A+C/2=125

75+C=250

C=250-75

= 175

Answer 2

The atomic mass of elements C is equal to 100.

Explanation:

The atomic masse of A = 75 and

The atomic masse of B = 125

To find, the atomic mass of elements C = ?

The atomic mass of elements C $= \dfrac{The atomic masse of A+The atomic masse of B}{2}$

$=\dfrac{75+125}{2}$

$=\dfrac{200}{2}$

= 100

∴ The atomic mass of elements C = 100

Thus, the atomic mass of elements C is equal to 100.
