The solids content of a stream water sample is to be determined. The total solids content is determined by placing a portion of the sample into a porcelain evaporating dish, drying the sample. at 105°c, and igniting the residue by placing the dried sample in a muffle furnace at 105°C. The following masses are recorded: mans of empty dish: 50.326 g mass of dish and ignited solids: 50,383 g • mass of dish and sample: 118.400 g mass of dish and dry solids: 50.437 g • a) The total solids content is: b) The total volatile solids content is: c) The fixed solids content is:

Question
1. The solids content of a stream water sample is to be determined. The total solids content is determined by
placing a portion of the sample into a porcelain evaporating dish, drying the sample. at 105°c, and igniting
the residue by placing the dried sample in a muffle furnace at 105°C. The following masses are recorded:
• mans of empty dish: 50.326 g
mass of dish and ignited solids: 50,383 g
P=118,400 g - 50,336 g = 68.074 ml
mass of dish and sample: 118.400 g
mass of dish and dry solids: 50. 437 g
a) The total
solids
content is:
(50.437g-50.326 g)
b) The total
volatile solids
content is:
c) The fixed
solids
content is:
