2 Experiment: In the experiment conducted, the mass of the counter weight M was chosen to be 50.0 +/- 0.1 g The mass of the rubber stopper was measured to be 12.0 +/- 0.1 g The stopper was spun at five different values of the radius (measured with a meter stick). For each value of r, the time to complete 10 full revolutions was measured with stopwatch. The following data was collected: 40.0 60.0 80.0 100.0 (cm) 1) 120.0 10.74...

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...

just need help with questions 3. a & b
always rate!!!
Introduction Titration is a common analytical technique that is used to verify the concentrations of chemicals before they are sold as commercial products, in a process known as quality control. In this lab, you will be using a redox titration to find the concentration of the strong oxidizing agent hypochlorite (CIO) which is the active ingredient in bleach. Oxidizing and reducing agents are often determined using a redox titration....
