Five different fertilizers were analyzed by two methods, Phosphate (P,Os) was analyzed using pravimetrie
analyse and spectrophotometric method. Analyze the results of the two meth
answer the following
questions
a) Calculate the average content of P¿Os in the fertilizers for each method. Compare the difference
between the two average values, (4 Marks)
b. 0.2045 g of sample was treated with precipitating agent that was used in part a. Determine the mass% of sulphate if the mass of the obtained product is 0.4485g (2 Marks)
b. 0.2045 g of sample was treated with precipitating agent that was used in part a. Determine the mass
% of sulphate if the mass of the obtained product is 0.4485g (2 Marks)
c. Use the average value of P¿Os and determine the average mass of elemental phosphorous (P) inthe analyzed fertilizers analyzed by gravimetric analysis if the average mass of the fertilizerssample was 5.5450 g. (4 Marks)
c. Use the average value of P¿Os and determine the average mass of elemental phosphorous (P) in
