3.77 moles of Fe contain 2.27×1024 atoms Fe .

To calculate the number of atoms in a sample, divide its weight in grams by the amu atomic mass from the periodic table, then multiply the result by Avogadro’s number: 6.02 x 10^23.

Elemental composition of *2Fe(NO3)2

A carbon dioxide molecule, which has the formula CO2, contains one carbon atom and two oxygen atoms. This information is contained in the subscripts after each element. A molecule of sucrose (C12H22O11) has 12 carbon atoms, 22 hydrogen atoms and 11 oxygen atoms.

the formula for aluminum sulfate is Al2(SO4)3. Then, in a formula unit of Al2(SO4)3 there are two aluminum ions and three sulfate ions; or two aluminum, three sulfur, and twelve oxygen atoms.

six carbon atoms are present in each molecule. As each molecule contains six carbon atoms, 12 H atoms and six O atoms. c.) total hydrogen atoms are present = 3*12 =36 H atoms.

Percent composition by element

The deep purple color of potassium permanganate is caused by the movement of an electron to a vacant d-orbital in the manganese atom. The transition occurs when the chemical is in the presence of light. This is confirmed by the empty 3d-orbital in manganese.

Ingestion of potassium permanganate may result in damage to the upper gastrointestinal tract. Also it may cause systemic toxic effects such as adult respiratory distress syndrome, coagulopathy, hepatic-renal failure, pancreatitis and even death in severe cases.

Potassium permanganate is used as a wet dressing for wounds on your skin’s surface that are blistered or oozing pus. Athlete’s foot and impetigo. Potassium permanganate can help to treat both bacterial and fungal skin infections such as athlete’s foot and impetigo.

Answer. Answer: if we add a drop of ink or a piece of potassium permanganate in water we see that the ink/Potassium Permanganate diffuses very fast in the solution and within a short period of time the entire solution gets coloured.

Potassium permanganate is a very strong oxidizing agent. So, it helps in the oxidation of dissolved iron, manganese, and hydrogen sulfide. Potassium permanganate also heps in controlling the growth of iron bacteria. Therefore, due to these reasons potassium permanganate is used during cleaning water tanks.

Officials say the purple water could stain your laundry. But besides that, there’s no real danger. “Once it’s diluted out, it’s not dangerous at all,” Stephen Burchett, water treatment plant operator, said.

You can wash fruits and vegetables under running water with a soft brush. You may also choose to use potassium permanganate to clean fruits and vegetables. Soak them in potassium permanganate for about five minutes and then rinse. This is very effective in washing away germs, bacteria and pesticides.

It is not necessary to rinse off with clean water. Use either warm or cool water to make the solution. Potassium permanganate may stain the skin, nails and light clothing a brown colour. To remove fresh stains from the skin, rub over with a damp tablet of vitamin C.

Hence, potassium permanganate should be used with caution as mouth gargle, antidote for poisoning, antiseptic and disinfectant. Adequate care should be exercised to avoid ingesting a dose that may be too toxic to the body.

You are advised to a Sitz bath every day, that is, sitting in a tub of warm water with potassium permanganate added to it for 20 minutes 2-3 times a day to keep the area clean and for relief from pain. You may experience pain, discomfort and a slight watery discharge from the operated site for 7-10 days.

Home remedies

• Eat high-fiber foods. Eat more fruits, vegetables and whole grains.
• Use topical treatments. Apply an over-the-counter hemorrhoid cream or suppository containing hydrocortisone, or use pads containing witch hazel or a numbing agent.
• Soak regularly in a warm bath or sitz bath.
• Take oral pain relievers.

It can be applied as a soaked dressing or a bath. Side effects may include irritation of the skin and discoloration of clothing. If it is taken by mouth, toxicity and death may occur. Potassium permanganate is an oxidizing agent.
