Please type out all of your calculations for this dilution equation: In your vitamin C experiment, it calls for a 5% concentration of iodine. However, your 7 fluid oz. tincture of iodine contains 70% iodine. How would you dilute this

The original7 fluid oz. 70% tincture of iodine is diluted to 98 fluid oz. to obtain a 5% solution.

Explanation:

Dilution is a technique employed in experimental sciences such as chemistry and biochemistry as well as in medicine to obtain a less concentrated solution from a more concentrated one.

The dilution formula is the most important formula required in dilution. The dilution formula is given as: C1V1 = C2V2

Where C1 is the initial concentration of the stock solution;

V1 is the volume of the stock solution required;

C2 is the final concentration of the diluted solution to be prepared;

V2 is the final volume of the diluted solution.

Using the dilution formula to determine the answer to the above question:

C1 = 70% = 0.7; V1 = 7 fluid oz.; C2 = 5% = 0.05; V2 = ?

To determine V2, it is made subject of the dilution formula:

V2 = C1V1/C2

V2 = (0.7 × 7) / 0.05

V2 = 98 fluid oz.

Therefore, the original7 fluid oz. 70% tincture of iodine is diluted to 98 fluid oz. to obtain a 5% solution.

the answer is c.the valence of the atoms combine .
