Answer:
18.8 mL
Explanation:
The dilution formula states that the product between the initial molarity and the initial volume should be equal to the product between the final molarity and the final volume, since the number of moles of a substance remains constant in a dilution process:
We are given the initial molarity of the stock solution , the final molarity of the diluted solution and the final volume of the diluted solution .
Rearranging the expression for the volume of the stock solution, we get:
Therefore, 18.8 mL of the stock solution are required.
In its elemental form, Iodine is a diatomic molecule in the gas phase. In the periodic table, Iodine is just right beside Xenon which is a stable element because it has no extra electrons. Thus, to conform to stability, Iodine must have to gain one more electron. That's why in its ionic form, its formula is I⁻. The reaction would be
I₂ → 2 I⁻
To achieve the Law of Definite Proportions from Dalton's Atomic Theory, we must balance the reaction. So in every neutral Iodine atom, 2 Iodide ions are formed.
The mantle is the mostly-solid bulk of Earth's interior. The mantle lies between Earth's dense, super-heated core and its thin outer layer, the crust. The mantle is about 2,900 kilometers (1,802 miles) thick, and makes up a whopping 84% of Earth's total volume.
