$F e S O_{4}$

Step 1

To find the mass of $1$ mole of $F e S O_{4}$ 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 $F e S O_{4}$ $=$ $(mass of Fe)$ + $(mass of S)$ + $4 (mass of O)$

Step 2

Fill in the atomic masses from the periodic table.

mass of $1$ mole of $F e S O_{4}$ $=$ $(55.84999847)$ + $(32.06999969)$ + $4 (16)$

Step 3.1

Remove parentheses.

mass of $1$ mole of $F e S O_{4} = 55.84999847 + 32.06999969 + 4 (16) g$

Step 3.2

Multiply $4$ by $16$ .

mass of $1$ mole of $F e S O_{4} = 55.84999847 + 32.06999969 + 64 g$

Step 3.3

Add $55.84999847$ and $32.06999969$ .

mass of $1$ mole of $F e S O_{4} = 87.91999816 + 64 g$

Step 3.4

Add $87.91999816$ and $64$ .

mass of $1$ mole of $F e S O_{4} = 151.91999816 g$
