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:
I am pretty sure the answer is A
