The value of
of
is 1.7×
.
So, option C is correct one.
Calculation,
Number of moles of
= mass/molar mass = 0.45/278.1 = 1.618×
moles
Concentration of
and
ion
Molarity of
= Number of moles of solute /volume in lit
Molarity of
= 1.618×
moles /0.1 lit = 0.0162 M
→
+ 2
For certain amount of
, twice this amount of
ion formed.
The concentration of
ion formed = 2× 0.0162 M = 0.0324 M
Now,
of
= [
]
= 0.0162 ×
= 1.7×
.
