Question

A student was tasked to perform gravimetric analysis of a soluble sulfate. His unknown sample weighed 0.7543 g. The sample underwent
precipitation using BaCl2 and was digested for overnight. The precipitate was then filtered off to obtain white crystalline precipitate that was collected in
an ash less filter paper. In performing constant weighing, he obtained a crucible mass that is 29.9442 g. After burning his samples inside the crucible,
the obtained mass was 30.3375 g.
29. Compute for the mass (g) of BaSO4 from the experiment.
A) 0.3933
B) 0.3393
C) 0.3133
D) 0.3951
E) 0.3591
30. Compute for the experimental mass (g) of SO3 in grams obtained by the student.
A) 0.1439
B) 0.1349
C) 0.1943
D) 0.1394
E) 0.3591
31. Compute for the experimental % SO3 obtained by the student.
A) 73.21
B) 56.33
C) 17.89
D) 56.89
E) 72.80
32. Compute for the theoretical % SO3 obtained by the student
A) 0.3933
B) 56.37
C) 17.33
D) 17.89
E) 0.4252
33. Compute for the theoretical mass (g) of SO3 that should be obtained by the student using his weighed sample.
A) 0.5367
B) 0.6827
C) 0.7543
D) 0.1134
E) 0.4252
34. Compute for the % error of the student in his analysis.
A) 53.67
B) 68.27
C) 75.43
D) 11.34
E) 42.52
