Question

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

Answer 1

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

Explanation:

Given: Percentage of sulfur present = 3%

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

$Percentage = \frac{32 g}{32 + 64} \times 100\\= 33.33 percent$

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

$\frac{3}{100} \times 33.33\\= 0.999 percent$

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