A student prepared 7.2 g of Co,(NH3),Cl . She then analyzed the compound to find the values of x, y, and z. In the gravimetric determination of chloride, she weighed out a 0.2988 g sample of the product compound and reacted it with AgNO3. The following data were obtained: Mass of crucible plus AgCl 19.0020 g Mass of crucible 18.4628 g a. Calculate the mass of...

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...

E: How many moles of aluminum ions are present in 0.32 moles of Al2(SO4)3? F: How many moles of sulfate ions (SO42?) are present in 1.3 moles of Al2(SO4)3? G: Calculate molar mass C6H14O6 (sorbitol) Express your answer to two decimal places and include the appropriate units. H: The sedative Demerol hydrochloride has the formula C15H22ClNO2. How many grams are in 0.025 moles of Demerol hydrochloride? I: How many moles of H2 are needed to react with 0.55 mol of...
