To what volume must 557 mL of 11 M

Ca (OH) 2 solution be diluted to make a 4 M

Ca (OH) 2 solution?

1. 1.90775

2. 2.9575

3. the correct answer is not given

4. 1.53175 L

5. 1.84067

The answer to your question is the number 4. 1.53175 L

Explanation:

Data

Volume 1 = V1 = 557 ml

Concentration 1 = C1 = 11 M

Volume 2 = V2 = ?

Concentration 2 = C2 = 4 M

Formula

Volume 1 x Concentration 1 = Volume 2 x Concentration 2

or V1 x C1 = V2 x C2

Solve for V2 V2 = V1 x C1 / C2

-Substitution

V2 = (557) (11) / 4

-Simplification

V2 = 6127 / 4

-Result

V2 = 1531.75 ml or 1.53175 L

Conclusion

557 ml of 11 M must be diluted to 1.53175 L
