Question

Equivalent weight of metal is 20.if the metal forms tripositive ion ,its atomic weight will be

Answer 1

Answer:

60

Explanation:

1. equi.mass=atomic mass/valency
2. 20=atomic mass/3
3. atomic mass= 20×3=60u

Answer 2

Answer:

60

Explanation:

therefore equivalent wt=MM / nf

thus 20 = MM / 3  

nf = no of electrons lost or gained

thus nf=3

so MM =20 * 3

ans is 60 amu
