Lab 3: Determination of Molar Mass by Freezing Point Depression 1 During winter, several different "salts" are used to melt ice sodium chloride (NaCI), a mix of sodium chloride and magnesium chloride (NaCl and MgCla calcium magnesium acetate (CaMg(CHO)). Assume you have 1 mole of each of these in 1 kg of water. Compare the freezing point depressions of these three "salts." a. b. What is the ratio of moles of "salt" to freezing point depression for each? What is...

A derivative of sucrose that is found in sugar beets and higher plants was analyzed and found to have the properties listed in the following. (a) Mol. Formula: C18H22O16 MW = 504.4 Assuming the compound is made up of C6 sugars, how many sugars to you expect to find in the molecule? (b) The compound was subjected to acid hydrolysis and gas chromatographic (GC) analysis of its sugar components by means of their per-O-trimethylsilyl ether derivatives. The sugar components...
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...
