What is the mass of 4.75 mol of the element iron (Fe)?
Answer in units of g
55.85 g/mol
would you mind explaining how you got that?
1 mol Fe has a mass of 55.85g. You get this by looking on the periodic table. Therefore, 4.75 mol has a mass of
4.75 mol x (55.85 g/mol) = ?grams.
To find the mass of 4.75 mol of iron (Fe), you'll need to know the molar mass of iron. The molar mass is the mass of one mole of a substance and is expressed in units of grams per mole (g/mol).
The atomic mass of iron (Fe) is approximately 55.845 g/mol according to the periodic table. This means that one mole of iron has a mass of 55.845 grams.
To calculate the mass of 4.75 mol of iron, you can use the following formula:
Mass = Number of moles × Molar mass
Substituting the values, we have:
Mass = 4.75 mol × 55.845 g/mol
Evaluating the expression:
Mass = 265.10375 g
Therefore, the mass of 4.75 mol of iron (Fe) is approximately 265.10375 grams (g).
