Answer:
136.36 mL
Explanation:
Here we have to use the dilution formula
From C1V1= C2V2
Where;
C1= initial concentration of the solution= 12.0 M
C2= final concentration of the solution= 2.20 M
V1 = initial volume of the solution= 25.0 ml
V2= final volume of the solution= ?????
Then recall;
C1V1=C2V2
V2 = C1V1/C2
Substituting values from the parameters given;
V2= 12.0 × 25.0 / 2.20
V2= 136.36 mL
Answer:
Sn(C2H3O2)2
Explanation:
C2H3O2 is Acetate
Sn is tin
Acetate has a -1 charge
In order for tin to have a +2 charge, we need two acetates
So we write it as (C2H3O2)2
You just leave Sn blank because of the roman numeral and since it is a transition metal.
So the answer is Sn(C2H3O2)2
