m_cup = ___19.6______ g

Analysis:

Here are the accepted values for the specific heat of each specimen:

A: Zinc, specific heat = 0.093

B: Aluminum, specific heat = 0.210

C: Iron, specific heat = 0.110

D: Copper, specific heat = 0.093

E: Brass, specific heat = 0.090

Calculate the % errors for each of your ‘c’ values.

Solving for c_s, the specific heat of the unknown specimen,

The following measurements are given in the data table below: mass of the Styrofoam cup, mass of the specimen, mass of the water, initial and final temperature of the water.

Calculate: the change in temperature of the water, the change in temperature of the specimen (it starts at the boiling point of water, 100 degrees C), the total heat transferred to the water, and the specific heat of the specimen.

A 0.7257 g mixture of KCN (MW = 65.116 g/mol) and NaCN (MW = 49.005 g/mol) was dissolved in water. AgNO3 was added to the solution, precipitating all the CN– in solution as AgCN (MW = 133.886 g/mol). The dried precipitate weighed 1.650 g. Calculate the weight percent of KCN and NaCN in the original sample.

A sample containing a mixture of SrCl2·6H2O (MW = 266.62 g/mol) and CsCl (MW = 168.36 g/mol) originally weighs 1.7215 g. Upon heating the sample to 320 °C, the waters of hydration are driven off SrCl2·6H2O, leaving the anhydrous SrCl2. After cooling the sample in a desiccator, it has a mass of 1.2521 g. Calculate the weight percent of Sr, Cs, and Cl in the original sample.

If you are given the following solids: Na3PO4 MW = 163.94 g/mol K3PO4 MW = 212.26

If you are given the following solids: Na3PO4 MW = 163.94 g/mol K3PO4 MW = 212.26 g/mol NaH2PO4 MW = 119.98 g/mol K2HPO4 MW = 174.17 g/mol Na2HPO4 MW = 141.96 g/mol KH2PO4 MW = 136.08 g/mol Which compounds would you use to prepare your stock solutions? Why? I picked KH2PO4 and K2HPO4 because potassium salts dissolve more readily in H2O which would make the lab go more smoothly. I would like to know if I'm missing any...
