need help with #5,6,7 and 8

Experimental Procedure 2. Obtain a sample of CuSO4,5H2O from your tray or instructor. Weigh, to 0.001g1.500g sample on a weighing paper. 3. Weigh an empty evaporating dish on the same balance. 4. Place the weighed sample in an evaporating dish and heat vigorously on a hot plate. Note any color change. 5. Stop heating after 5-10 minutes of vigorous heating. Let the product and the dish cool. 6. Weigh the new Acolde dish and its contents. 7. Repeat steps 5-6 until successive weights of dish plus sample give the same results. 8. After successive weight agreement record this weight. 9. Using the weight of the empty evaporating dish calculate the weight of the product. 10. Proceed to the calculations after the data table. A. Data acquisition: 1. Wt of evaporating dish 36.139 g. B. Calculations 1. Using stoichiometry and the reaction equation, calculate the weight of product theoretically obtainable from the starting weight of CuSO4.5H2O. 2. Compare this theoretical weight to the experimental weight obtained in part A above. 3. Are both the theoretical and experimental weights of the products the same? If not calculate the \% error of your experimental weight compared to the theoretical weight 4. Give reasons why both weights are not the same. 5. Calculate the % product in the original CuSO4.5H2O sample. 6. Calculate the mass of water produced 7. Calculate the % of H2O in the sample. 8. Does the %H2O agree with the theoretical %H2O indicated by the formula CuSO4.5H2O
