Kian is working in the lab with a 9.50M stock solution. If he makes a solution with a volume of 1.25L and a molarity of 3.00M, what was the volume of his stock solution?
Answers
Answer :
The stock solution occupies 3.96 L
Given :
Kian prepares a 3.00 M solution from a 9.50 M stock solution which occupies 1.25 L
Explanation :
We have to find the volume occupied by the 3.00 M stock solution
Dilution Equation
Substituting the values,
...

This question can be solved very easily by using the Dilution Equation.
- Dilution Equation -
Where -
C_{1} and C_{2} are the respective concentrations .
V_{1} and V_{2} are the respective volumes.
Here -
C_{1} = 9.50 M
C_{2} = 3.00 M
V_{1} = ?
V_{2} = 1.25 L
Substuting the required values in the above Equation -
We obtain -
V_{1} = 3.96 litres
