A) 80 liters

B) 60 liters

C) 100 liters

D) 120 liters

Answer 1

A 4.0-liter jug of bleach can treat approximately 26666.67 liters of water.

Step-by-step explanation:

Household bleach can be used to disinfect water for drinking. It is recommended that 3 drops of bleach be added to each liter of water. Given that 1 mL is equal to 20 drops, we can calculate that 3 drops is equal to 0.15 mL. Therefore, a 4.0-liter jug of bleach can treat 600 liters of water. To find this, we divide the volume of bleach (4.0 liters) by the volume of bleach needed per liter of water (0.15 mL).

1. First, we convert the volume of bleach needed per liter of water to liters: 0.15 mL / 1000 mL/L = 0.00015 L.
2. Next, we divide the volume of bleach by the volume needed per liter of water: 4.0 L / 0.00015 L = 26666.67 liters.

Therefore, a 4.0-liter jug of bleach can treat approximately 26666.67 liters of water.
