FeCo3
Calculate the mass percent composition of iron for the third one of these iron ores.
I don't see any iron ores listed.
(siderite).FeCO3
%Fe = (atomic mass Fe/molar mass FeCO3)*100 = ??
To calculate the mass percent composition of iron (Fe) in FeCo3, we first need to determine the molar mass of FeCo3.
The molar mass of Fe is 55.845 g/mol, and the molar mass of Co is 58.933 g/mol. Since there are three oxygen atoms (O) in FeCo3, we need to consider their molar mass as well. The molar mass of O is 16.00 g/mol.
Now, we can calculate the molar mass of FeCo3 as follows:
Molar mass of FeCo3 = (molar mass of Fe) + (molar mass of Co) + (3 * molar mass of O)
= (55.845 g/mol) + (58.933 g/mol) + (3 * 16.00 g/mol)
= 55.845 g/mol + 58.933 g/mol + 48.00 g/mol
= 162.778 g/mol
Next, we need to determine the mass of iron (Fe) in FeCo3. In FeCo3, there is only one iron atom.
The mass percent composition of iron (Fe) in FeCo3 can be calculated using the following formula:
Mass percent composition of Fe = (mass of Fe / molar mass of FeCo3) * 100
To calculate the mass percent composition of Fe, we need the mass of Fe (which is equal to its molar mass) and the molar mass of FeCo3. We already know that the molar mass of FeCo3 is 162.778 g/mol.
Therefore, the mass percent composition of Fe in FeCo3 can be calculated as:
Mass percent composition of Fe = (55.845 g/mol / 162.778 g/mol) * 100
= 34.28%
So, the mass percent composition of iron (Fe) in FeCo3 is approximately 34.28%.
