Question

1 gram of metal oxide give 0.2 grams of metal then the equivalent weight of metal is​

Answer 1

Answer:

weight of oxygen=1.0−0.2=0.8g=1.0-0.2=0.8g

Let the equivalent weight of metal (M) be E, Ew (oxygen) =8g=8g

Equivalent of metal oxide==equivalent of meta

weight of metal oxideEw(M)+Ew(O)=weight of oxygenEw(O)weight of metal oxideEw(M)+Ew(O)=weight of oxygenEw(O)

1.0E+8=0.88=0.11.0E+8=0.88=0.1

0.1(E+8)=1.00.1(E+8)=1.0

E=2E=2

Second method:

Eq. of metal == " Eq of "oxygen

Weight of MEw(M)=weight of oxygenEw(O)Weight of MEw(M)=weight of oxygenEw(O)

0.2E=0.880.2E=0.88

E=2
