Question

The amount of chlorine in a swimming pool varies directly with the volume of water. the pool has 2.5 milligrams of chlorine per liter of water. there are 8000 gallons of water in the swimming pool. how much chlorine is in the pool? round to the nearest thousand milligrams.

Answer 1

1 gallon = 3.785 liters
Water in pool = 8000 x 3.785
Water in pool = 30,280 liters

Chlorine dosage = 2.5 mg / liter
Chlorine = 2.5 x 30,280
Chlorine = 75,700 mg
To the nearest thousand milligram:
Chlorine = 76,000 mg
