Find the Mass of 1 Mole KMnO_4

$K M n O_{4}$

Step 1

To find the mass of $1$ mole of $K M n O_{4}$ 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 $K M n O_{4}$ $=$ $(mass of K)$ + $(mass of Mn)$ + $4 (mass of O)$

Step 2

Fill in the atomic masses from the periodic table.

mass of $1$ mole of $K M n O_{4}$ $=$ $(39.09999847)$ + $(54.93999862)$ + $4 (16)$

Step 3

Simplify the result.

Remove parentheses.

mass of $1$ mole of $K M n O_{4} = 39.09999847 + 54.93999862 + 4 (16) g$

Multiply $4$ by $16$ .

mass of $1$ mole of $K M n O_{4} = 39.09999847 + 54.93999862 + 64 g$

Add $39.09999847$ and $54.93999862$ .

mass of $1$ mole of $K M n O_{4} = 94.0399971 + 64 g$

Add $94.0399971$ and $64$ .

mass of $1$ mole of $K M n O_{4} = 158.0399971 g$
