Answer:
Explanation:Three atoms of M combine with 2 atoms of N.
Equivalent weight of N=
3 *14
(valency of N in compound = 3)
28g N combines with 72g metal.
3 *14
N combines =
28
72 × 3
14 =12
The equivalent weight of metal =12
Atomic mass of metal = equivalent weight × valency=12×2=24.
Hence, option A is correct.
