A hydrated form of copper sulfate (CuSO4⋅?H2O) is heated to drive off all of the water. If there is initially 7.28 g of hydrated salt and there is 4.07 g of anhydrous CuSO4 after heating, find the number of water molecules associated with each CuSO4 formula unit. x = ?
A mixture of CuSO4 and CuSO4 5 H2O has a masS of 1.270 g. After heating to drive off all the water, the mass is only 0.859 g. What is the mass percent of CuSO4 5 H2O in the mixture? Mass percent
You need to prepare 200ml of a 0.4M solution of copper sulfate (CuSO4). You have 80mL of a 0.5M CuSO4 solution and 100ml of 7.5% (w/v) CuSO4 solution. What volume of 7.5% CuSO4 and water needs to be added to the 80mL of 0.5M CuSO4 solution to make up 200mL of 0.4M CuSO4? Molar mass of CuSO4 = 159.609 g/mol % (weight/volume) means mass (in g) in volume (100mL)
1. The experiment's Standard 1 consists of 0.54 M CuSO4. What will be the concentration of Standard 2 if it is prepared by combining 10.0 mL of Standard 1 with 10.0 mL deionized water? 2. A student makes a solution for analysis by mixing 5.47 grams of Cu2SO4 into 408.2 grams of water. The density of water at the temperature of the lab at the time the solution was made is 0.9926 g/mL. Calculate the molarity, molality, mole fraction, and...
A student is given a sample of CuSO4(s) that contains a solid impurity that is soluble and colorless. The student wants to determine the amount of CuSO4 in the sample and decides to use a spectrophotometer. First, the student prepares a calibration graph by measuring the absorbances of CuSO4(aq) solutions of known concentrations. The graph is shown below.a) (a) The student dissolves the entire impure sample of CuSO4(s)CuSO4(s) in enough distilled water to make 100.mL100.mL of solution. Then the student...
