How many atoms are there in 38 g of iron(Fe) please help

Chemistry
1 answer:
garik1379 [7]3 years ago
4 0

Answer:

Explanation:

1 mole of iron is 56 grams (rounded)

x mole of iron is 38 grams (given

1/x = 56/38                Cross multiply

56x = 38*1                Divide by 56

x = 38/56

x = 0.679 mols of iron

1 mol of anything = 6.02 * 10^23

0.678 mols of iron = x

1/0.679 = 6.02 *10^23 /x

x = 0.679 * 6.02*10^23

x = 4.09 * 10 ^23

So there are 4.09 * 10^23 atoms of Fe in 38 grams of iron

Include a map with points where neon can be found.
nalin [4]
Here is some information: "Neon is a chemical element with symbol Ne and atomic number 10. It is in group 18 of the periodic table. Neon is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of air. It was discovered in 1898 as one of the three residual rare inert elements remaining in dry air, after nitrogen, oxygen, argon and carbon dioxide were removed. Neon was the second of these three rare gases to be discovered, and was immediately recognized as a new element from its bright red emission spectrum. The name neon is derived from the Greek word, νέον, neuter singular form of νέος, meaning new. Neon is chemically inert and forms no uncharged chemical compounds. The compounds of neon include ionic molecules, molecules held together by van der Waals forces and clathrates."

Also: "Neon is rare on Earth, found in the Earth's atmosphere at 1 part in 55,000, or 18.2 ppm by volume (this is about the same as the molecule or mole fraction), or 1 part in 79,000 of air by mass."

Also I only found one if that is okay but here it is: It is the place where it is a city and most people find most neon there.
