$M n F e$

Step 1

To find the mass of $1$ mole of $M n F e$ look up the atomic mass of each element and multiply it by the number of atoms contained in each element in the molecule.

mass of $1$ mole of $M n F e$ $=$ $(mass of Mn)$ + $(mass of Fe)$

Step 2

Fill in the atomic masses from the periodic table.

mass of $1$ mole of $M n F e$ $=$ $(54.93999862)$ + $(55.84999847)$

Step 3
