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:
B. It shows the ratio of elements in the compound.
Explanation:
Empirical formula tells about the ration of the elements found in the compound . The ratio are in complete number .
For example the molecular formula of glucose is C₆ H₁₂O₆
Its empirical formula = CH₂O
