Question

In some areas, drinking water is fluoridated to reduce tooth decay. The maximum acceptable concentration (MAC) of fluoride ions in

drinking water is 1.50 ppm.
In Dublin, California, a malfunction occurred in the fluoridation equipment caused fluoride levels to rise as high as 200 ppm. This
resulted in many people becoming ill.
During the malfunction, 660 kg of fluoride ions where injected into a storage tank of water. Given that the resulting concentration was
200 ppm, calculate the volume, in ML, of the water storage tank.
Record only your numerical answer with the correct number of significant digits.

Answer 1

To calculate the volume of the water storage tank, we can use the formula:

To calculate the volume of the water storage tank, we can use the formula:Volume (in mL) = Mass of fluoride ions injected (in g) / Concentration of fluoride ions (in ppm)

To calculate the volume of the water storage tank, we can use the formula:Volume (in mL) = Mass of fluoride ions injected (in g) / Concentration of fluoride ions (in ppm)First, let's convert the mass of fluoride ions from kg to grams:

To calculate the volume of the water storage tank, we can use the formula:Volume (in mL) = Mass of fluoride ions injected (in g) / Concentration of fluoride ions (in ppm)First, let's convert the mass of fluoride ions from kg to grams:660 kg = 660,000 grams

To calculate the volume of the water storage tank, we can use the formula:Volume (in mL) = Mass of fluoride ions injected (in g) / Concentration of fluoride ions (in ppm)First, let's convert the mass of fluoride ions from kg to grams:660 kg = 660,000 gramsNow, we can calculate the volume:

To calculate the volume of the water storage tank, we can use the formula:Volume (in mL) = Mass of fluoride ions injected (in g) / Concentration of fluoride ions (in ppm)First, let's convert the mass of fluoride ions from kg to grams:660 kg = 660,000 gramsNow, we can calculate the volume:Volume = 660,000 g / 200 ppm

To calculate the volume of the water storage tank, we can use the formula:Volume (in mL) = Mass of fluoride ions injected (in g) / Concentration of fluoride ions (in ppm)First, let's convert the mass of fluoride ions from kg to grams:660 kg = 660,000 gramsNow, we can calculate the volume:Volume = 660,000 g / 200 ppmVolume ≈ 3300 mL

To calculate the volume of the water storage tank, we can use the formula:Volume (in mL) = Mass of fluoride ions injected (in g) / Concentration of fluoride ions (in ppm)First, let's convert the mass of fluoride ions from kg to grams:660 kg = 660,000 gramsNow, we can calculate the volume:Volume = 660,000 g / 200 ppmVolume ≈ 3300 mLSo, the volume of the water storage tank is approximately 3300 mL.
