We have to know the product formed on reaction of ethyl iodide with triethylamine.
The product is tetraethylammonium iodide salt.
On reaction of ethyl iodide with triethylamine, a quarternary salt is produced which is ionic in nature. The salt is ionic and polar, it gets dissolved in polar solvent but insoluble in non-polar solvent.
As it is ionic compound, its melting point is high, it does not melt below 200°C.
The structure of the product (tetraethylammonium iodide salt) is shown below:
Answer: Uranium enrichment. Uranium is used to fuel nuclear reactors; however, uranium must be enriched before it can be used as fuel. Enriching uranium increases the amount of uranium-235 (U235) that can sustain the nuclear reaction needed to release energy and produce electricity at a nuclear power plant.
Take 58.5 and divide that by 0.5, we get 117 grams of Sodium Iodide per liter
If you are looking for molarity. Then there are 149.88 grams in one mole of Sodium Iodide. We have 0.78 moles of sodium iodide. Divide that by 0.5 liters (also dm3)
0.78 / 0.5 = 1.56 M
