the coal sample being used in this experiment is assumed to have 3% sulfur in its composition. what percent of sulfate is present in the coal samples

Sagot :

Answer: The percent of sulfate is present in the coal samples is 0.999%.

Explanation:

Given: Percentage of sulfur present = 3%

In [tex]SO^{2-}_{4}[/tex], the percentage by weight of Sulfur is calculated as follows.

[tex]Percentage = \frac{32 g}{32 + 64} \times 100\\= 33.33 percent[/tex]

This means that the amount of only sulfur present in [tex]SO^{2-}_{4}[/tex] in the sample is as follows.

[tex]\frac{3}{100} \times 33.33\\= 0.999 percent[/tex]

Thus, we can conclude that percent of sulfate is present in the coal samples is 0.999%.
