Answer :
Final answer:
The molarity of the solution after dilution to the given final volumes are approximately:
a. 0.76 M
b. 0.44 M
c. 0.064 M
d. 0.021 M
Explanation:
To calculate the molarity of the solution after dilution, we can use the formula:
M₁V₁ = M₂V₂
Where:
- M₁ is the initial molarity of the solution
- V₁ is the initial volume of the solution
- M₂ is the final molarity of the solution
- V₂ is the final volume of the solution
Let's calculate the molarity for each of the given final volumes:
a. 57.7 mL:
Using the formula, we have:
1.25 M x 35.0 mL = M₂ x 57.7 mL
Solving for M₂:
M₂ = (1.25 M x 35.0 mL) / 57.7 mL
M₂ ≈ 0.76 M
b. 98.1 mL:
Using the formula, we have:
1.25 M x 35.0 mL = M₂ x 98.1 mL
Solving for M₂:
M₂ = (1.25 M x 35.0 mL) / 98.1 mL
M₂ ≈ 0.44 M
c. 680 mL:
Using the formula, we have:
1.25 M x 35.0 mL = M₂ x 680 mL
Solving for M₂:
M₂ = (1.25 M x 35.0 mL) / 680 mL
M₂ ≈ 0.064 M
d. 2.06 L:
Using the formula, we have:
1.25 M x 35.0 mL = M₂ x 2.06 L
Solving for M₂:
M₂ = (1.25 M x 35.0 mL) / 2.06 L
M₂ ≈ 0.021 M
