Determine the mass of iron required to obtain 43.5 g of iron (III) chloride.
April 25, 2021 | education
| From 1 mole of iron, 1 mole of its chloride can be synthesized.
Let’s calculate the chemical amount of a substance in 43.5 grams of ferric chloride.
M FeCl3 = 56 + 35.5 x 3 = 162.5 grams / mol;
N FeCl3 = 43.5 / 162.5 = 0.268 mol;
The same amount of iron is needed.
Let’s calculate its weight.
M Fe = 56 grams / mol;
m Fe = 56 x 0.268 = 15 grams;
