Chemistry

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
3.7570.0
4.0060.0
4.2552.0
4.5045.0
4.7540.0
5.0036.0

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.
