Academics

Problem- A concentration of 1ppm of fluorine is sufficient for the purpose (1ppm means one part per million, or 1g of fluorine per 1 million g of water). Calculate the quantity of sodium fluoride in kilograms needed per year for a city of 50,000 people if the daily consumption of water per person is 165 gallons. (Sodium fluoride is 45% fluorine by mass. 1 gallon=3.79L; 1 ton= 2000lb; 1lb=453.6g; density of water =1g/mL
