Question

How many L of a 7.5 H2SO4 stock solution would you need to prepare a dilute solution 100 L of 0.25M H2SO4

Answer 1

3.33 L

Step-by-step explanation:

We can solve this problem by using the equation:

• C₁V₁=C₂V₂

Where the subscript 1 refers to one solution and subscript 2 to the another solution, meaning that in this case:

• C₁ = 0.25 M

• V₁ = 100 L

• C₂ = 7.5 M

• V₂ = ?

We input the data:

• 0.25 M * 100 L = 7.5 M * V₂

• V₂ = 3.33 L

Thus the answer is 3.33 liters.
