A mole of magnesium (Mg) and a mole of iron (Fe) both represent an amount of substance defined by Avogadro's number, which is approximately (6.022 \times 10^{23}) atoms. This means each mole contains the same number of atoms, regardless of the element. Additionally, both elements are metals found in the Periodic Table and can participate in chemical reactions, forming various compounds. Their molar masses differ, with magnesium being lighter than iron.

How many atoms in 10 mg of iron?
10 milligrams iron (1 gram/1000 milligrams)(1 mole Fe/55.85 grams)(6.022 X 1023/1 mole Fe) = 1.1 X 1020 atoms of iron ===================
How many moles of Fe and S are contained in one mole of FeS2?
the atomic mass of FeS2 is 110. You cannot find the no. of moles in a mole of FeS2 coz it is only a mole.
In the balanced reaction shown the mole ratio of fe2S3 to O2 is?
To determine the mole ratio of Fe₂S₃ to O₂ in a balanced chemical reaction, you need to look at the coefficients in the balanced equation. For example, if the balanced equation is 4 Fe₂S₃ + 12 O₂ → 8 Fe₂O₃ + 6 SO₂, the mole ratio of Fe₂S₃ to O₂ would be 4:12, which simplifies to 1:3. Therefore, the mole ratio of Fe₂S₃ to O₂ is 1:3.

What mole ratio would you use to determine moles Fe if moles Fe2O3 is known?
If the moles of Fe2O3 are known, you would use the mole ratio from the balanced chemical equation for the reaction involving Fe2O3 and Fe. In the balanced equation, the mole ratio between Fe2O3 and Fe is 2:2, which simplifies to 1:1. This means that for every mole of Fe2O3, there is an equivalent mole of Fe.

How many iron atoms are present in a 23.0 g iron block?
To determine the number of iron atoms in a 23.0 g iron block, you would first calculate the number of moles of iron using the molar mass of iron (55.85 g/mol). Then, you would use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles of iron to atoms.
How many moles of Cl are in NaCl?
The formula weight of NaCl is 58.44 which means 58.44 g = 1 mole. Since 1000 mg = 1 g, this gives 58.44 g/mole x 1000 mg/g = 5.844 E+4 mg/mole. Then, 52.1 mg NaCl x 1 mole NaCl/5.844E+4 mg = 8.92 E-4 mole. See, this is just done by using the definitions of the units and the factor label method to analyze the conversion.
