Coal has an energy content of approximately 2.4 x 107 j/kg, and about 4% sulfur content by mass. if coal-fired power plants in the united states produce around 2.6 x 1011 watts of electricity, how many kilograms of sulfur will be emitted from coal plants in two weeks? note that 1 j = 1 w·sec.

kilograms of sulfur will be emitted from coal plants in two weeks

Explanation:

Power produced by power plants in the United States :P

P=

1 Joule = Watts × Seconds

Watts = Joule/Second

P=

This means that Joules of enrgy is produced in one second.

So, energy produced in 2 week:

1 week = 7 days

1 day  =  24 hours

1 hour = 3600 seconds

2 week = 2 × 7 × 24 × 3600 s=1,209,600 s

Energy produced in 1,209,600 s: E

Coal has an energy content =

Mass of coal used while producing E amount of energy: m

Percentage of sulfur in coal = 4% by mass

Mass of sulfur produced from in 2 weeks:
