A sample of CaCl2⋅2H2O/K2C2O4⋅H2O solid salt mixture is dissolved in ~100 mL de-ionized H2O. The oven dried precipitate has a mass of 0.233 g. The limiting reactant in the salt mixture is K2C2O4⋅H2O. CaCl2⋅2H2O(aq) + K2C2O4⋅H2O(aq) --> CaC2O4⋅H2O(s) + 2KCl(aq) + 2H2O(l) starting material (SM) product Molar Mass (MM) g/mol: CaCl2⋅2H2O = 147.02 K2C2O4⋅H2O = 184.24 CaC2O4 = 128.10 Determine Mass ofK2C2O4⋅H2O(aq) in Salt Mixture in grams. Answer to 3 places after the decimal and include unit, g Do calculation all at once, round off at the end. |

I need helppp with my AP chem lab
Purpose: To calculate the amount of AgNO3 present in an unknown solution of water through the process of gravimetric analysis with NaCl. Background: Have you ever had difficulty lathering soap or find that the scum in your shower constantly needs to be removed? These are signs of “hard water.” Soap does not lather well in hard water because metal ions, such as Ca2+, form precipitates, creating “soap scum.” A precipitate is an insoluble compound that forms when soluble ions in...
