What is the total mass of iron in 1.0 mole of FeCO3?
(1.0 mole FeCO3)(1 mol Fe/ 1 mol FeCO3)(molar mass Fe/ 1 mol Fe)
To find the total mass of iron in 1.0 mole of FeCO3 (iron(II) carbonate), we need to calculate it based on the molar mass.
To start, we need to determine the molar mass of FeCO3. The molar mass of each element is found on the periodic table.
Fe: Iron has an atomic mass of 55.85 g/mol.
C: Carbon has an atomic mass of 12.01 g/mol.
O: Oxygen has an atomic mass of 16.00 g/mol.
Next, we add up the atomic masses of each element within the formula FeCO3:
Fe: 1 atom x 55.85 g/mol = 55.85 g/mol
C: 1 atom x 12.01 g/mol = 12.01 g/mol
O: 3 atoms x 16.00 g/mol = 48.00 g/mol
Now, we sum up the individual masses:
55.85 g/mol + 12.01 g/mol + 48.00 g/mol = 115.86 g/mol
The molar mass of FeCO3 is 115.86 g/mol.
Since the molar mass of FeCO3 is 115.86 g/mol, we know that 1.0 mole of FeCO3 will have a mass of 115.86 grams. However, we are interested in the total mass of iron. To find that, we need to know the molar mass ratio between iron and FeCO3.
In the formula FeCO3, there is one iron atom (Fe), so the ratio of the molar masses is 1:1. This means that the mass of iron in 1.0 mole of FeCO3 will also be 115.86 grams.
Therefore, the total mass of iron in 1.0 mole of FeCO3 is 115.86 grams.
