Find the Mass of 1 Mole Na_2S

$N a_{2} S$

Step 1

To find the mass of $1$ mole of $N a_{2} S$ 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 $N a_{2} S$ $=$ $2 (mass of Na)$ + $(mass of S)$

Step 2

Fill in the atomic masses from the periodic table.

mass of $1$ mole of $N a_{2} S$ $=$ $2 (22.98999977)$ + $(32.06999969)$

Step 3

Simplify the result.

Remove parentheses.

mass of $1$ mole of $N a_{2} S = 2 (22.98999977) + 32.06999969 g$

Multiply $2$ by $22.98999977$ .

mass of $1$ mole of $N a_{2} S = 45.97999954 + 32.06999969 g$

Add $45.97999954$ and $32.06999969$ .

mass of $1$ mole of $N a_{2} S = 78.04999923 g$
