3 FAQs about [Two solid samples each contain sulfur]
How is the sulfur content of a sample determined?
The sulfur content of a sample can be easily determined using the Parr oxygen combustion bomb method. The sample preparation takes approximately 20 minutes. The sulfur content can be determined using simple aqueous solutions as calibration standards.
How many moles of sulphur are present in a sample?
A given sample of sulphur contains 0.25 mol of sulphur molecules. The number of moles of sulphur atoms, number of sulphur molecules and number of sulphur atoms present in the given sample are respectively 206 g of molten sodium bromide is decomposed electrolytically. The maximum mass of sodium obtained is . . . . I only.
How much soluble sulphate was present in all samples?
All samples contained small amounts of soluble sulphate (< 1 wt.%). The amount of organic carbon ranged between 0.1 and 0.3 wt.%, and the amount of total iron ranged between 2.9-3.9 wt.%. Iron was mostly in ferric form in all samples (Tables 7 and 8).
