The equivalent weight of a certain trivalent element is 20

1.	The equivalent weight of a certain trivalent element is 20
Answer» As the valency is 3, the oxide will be M2O3. If 3 atoms of oxygen are used then they are 6 EQUIVALENTS. So, 6 equivalents of the element will also be used, molecular WEIGHT= 620+ 68= 120+48=168.

Answer»

As the valency is 3, the oxide will be M2O3.

If 3 atoms of oxygen are used then they are 6 EQUIVALENTS. So, 6 equivalents of the element will also be used,

molecular WEIGHT= 6*20+ 6*8= 120+48=168.
