How many atoms are there in 1.0 gram of iron, Fe?

Therre are 6.023 x 10^23 atoms in 1 mol of Fe atoms and 1 mol of Fe atoms has a mass of 55.85 grams. Convert 1.0 g Fe atoms to mols and convert that to number of atoms. Post your work if you get stuck.

Yeah I knew that but I don't have a scientific calculator with me. Do you think you could do the math for me?

Nevermind I got it =)

When you get stuck without a calculator, you can always go to google and use that in a pinch. Google is good, also, for conversions from one unit to another. Try it, you'll like it.

To determine the number of atoms in 1.0 gram of iron (Fe), we can follow these steps:

Step 1: Find the molar mass of iron (Fe)

The molar mass of an element represents the mass of one mole of that element. The molar mass of iron (Fe) can be found on the periodic table, which is approximately 55.845 grams per mole (g/mol).

Step 2: Convert grams to moles

To convert grams of iron to moles, we divide the given mass (1.0 gram) by the molar mass of iron (Fe) (55.845 g/mol):

1.0 gram / 55.845 g/mol ≈ 0.0179 moles

Step 3: Determine Avogadro's number

Avogadro's number is defined as the number of atoms or molecules in one mole of a substance. It is approximately 6.022 × 10^23.

Step 4: Calculate the number of atoms

To find the number of atoms in the given moles, we multiply the moles (0.0179) by Avogadro's number:

0.0179 moles * 6.022 × 10^23 atoms/mol ≈ 1.08 × 10^22 atoms

Therefore, there are approximately 1.08 × 10^22 iron atoms in 1.0 gram of iron (Fe).
