Problem: The mass percent of sulfur in a sample of coal is a key factor in the environmental impact of the coal because the sulfur combines with oxygen when the coal is burned and the oxide can then be incorporated into acid rain. Which of the following coals would have the smallest environmental impact?

FREE Expert Solution

We are asked to determine which of the coals would have the smallest environmental impact and to do that we’re going to use the mass percent formula shown below:

mass percent=mass of componenttotal mass×100

For the percent by mass S, we’re going to rewrite the equation as:
