Presenting LSE Data

The most common presentation of LSE data is a table like Table 11.5. We see that the solubility of NaCl in water increases very slowly with increases in temperature. 

Example 11.10 Table 11.5 shows the most commonly reported unit for reporting such solubility. Show the corresponding values of the weight fraction and mol fraction of NaCl in a saturated solution in water at 20°C  

LIQUID-LIQUID, LIQUID OLID, AND GAS-SOLID EQUILIBRIUM 

This simple example is included to show the relations among the three most common ways of expressing LSE data.
