A bottle of ant killer holds 1,5L of concentrate. To make up a solution, 5 capfuls are added to 1L of water. Each capful is 25mL. How many litres of solutions can be made if you use the entire bottle of concentrate

1 answer

If the bottle of ant killer holds 1.5L of concentrate, and each capful is 25mL, then the total number of capfuls in the bottle of concentrate is 1.5L / 25mL/capful = 60 capfuls.
Since 5 capfuls are added to 1L of water to make a solution, then each solution requires 5 capfuls + 1L/0.025L/capful = 5 capfuls + 40 capfuls.
Therefore, each solution requires 45 capfuls/capful.
Hence, the total number of solutions that can be made from the entire bottle of concentrate is 60 capfuls / 45 capfuls/capful = <<60/45=1.3333333333333333>>1.33 liters. Answer: \boxed{1.33}.
