Answer:
TS (total solid, mg/L) = 57,174 mg/L
VS (volatile solid, mg/L) = 24,088 mg/L
Explanation:
First step to solve this problem is to know data and questions:
Data:
Sample volume = 50 mL
Sample weight = 50.1 g
P1 (weight empty crucible) = 17.1234 g
P2 (weight after drying a 103º in oven) = 19.9821 g
P3 (weight after incinatrion 550º) = 18.7777 g
Questions:
TS = ?
VS = ?
Formula:
We need to use formulas to calculate total solid (TS) and volatile solid (VS), these are:
We have to transform mL to L so we will divide mL by 1,000 the sample volume:
In the formula the value of 1,000 results by the convertion factor to transform grams to miligrams (we have to multiplie by 1,000)
Now we need to replace data on previous formulas and we will get TS and VS expressed in mg/L:
We divide TS and VS formula by sample volume because the exercise is asking us to express the results in mg/L.
