![**Converting between Grams and Moles**
**Learning Goal:**
The conversion factor between mass and number of moles is called molar mass. By consulting the periodic table, we can determine that the molar mass of NaCl is:
\[ 23.0 \, \text{g/mole} + 35.5 \, \text{g/mole} = 58.5 \, \text{g/mole} \]
This number tells us that 1 mole of NaCl has a mass of 58.5 g. The conversion factors are:
\[ \frac{58.5 \, \text{g}}{1 \, \text{mole}} \quad \text{and} \quad \frac{1 \, \text{mole}}{58.5 \, \text{g}} \]
Here is an example of the conversion of 12.0 moles of NaCl to grams using the first conversion factor:
\[ 12.0 \, \text{moles} \times \frac{58.5 \, \text{g}}{1 \, \text{mole}} = 702 \, \text{g} \]
