The data below was collected in an experiment to determine thesolubility of sodium nitrate at 20 Celsius degree.
| Total Volume of Water (mL) | Saturation Temp (Celsius degree) | Solubility (g salt/100g water) |
3.50 | 78.0 | |
| 3.75 | 70.0 | |
| 4.00 | 60.0 | |
| 4.25 | 52.0 | |
| 4.50 | 45.0 | |
| 4.75 | 40.0 | |
| 5.00 | 36.0 | |
1. If 5.0000g of NaNO3 was used, calculate the solubility inunits of g NaNO3/100g water at each saturation temperature. Showyour first calculation. Complete the rest of the calculations andfill in the table.
2. Construct a graph of solubility as a function ofsaturation.
3. Determine the solubility of sodium nitrate at 20 Celsiusdegree from a graph.
4. Using the solubility from #3, calculate the percent by massof the salt in a saturated solution at 20 Celsius degree.
5. If the density of a saturated solution of sodium nitrate at20 Celsius degree is found to be 1.4g/mL, calculate the Molarity ofthe solution.
