Answer:
35.5
⋅
y
x
−
y
g
Explanation:
For this compound, the equivalent mass of the metal represents the mass of metal that combines with exactly
35.5 g
of chlorine.
You know that the total mass of the oxide is equal to
x
g
and that this sample contains
y
g
of metal, so you can say that the mass of chlorine present in the sample is equal to
mass of metal chloride
x
.
g
−
mass of metal
y
.
g
=
mass of chlorine
(
x
−
y
)
.
g
So, you know that
y
g
of metal combine with
(
x
−
y
)
g
of chlorine, so you can say that
35.5 g
of chlorine will combine with
35.5
g Cl
⋅
y
.
g metal
(

)
g Cl
=
(

.
g metal
Therefore, the equivalent mass of the metal in this compound is equal to
