mass of evaporating dish 42.3g
volume of NaCl solution 20.00mL
Mass of evaporating dish and NaCl (after heating) 51.07g
Mass of Nacl 8.77g
1. Using the equation, Ksp = [Na+][Cl-], calculate the Ksp of NaCl using the data in your data table. This will be your observed value. Ksp = ?
2. Given that the solubility of NaCl is 35.7 g/100 mL solution, calculate the “accepted” value of the Ksp of NaCl. Ksp = ?
3. Calculate your percentage error using the equation below: % Error = (Observed - Accepted)/ Accepted x 100 % Error =?
