A pure sample of a compound containing only P and F is analyzed to determine the elemental composition and find the empirical formula. however, this requires two separate analyses. The first converts all the fluorine in the sample to silver fluoride, AgF. A sample weighing 0.3271 g gives 0.6219 g AgF. The second sample, with a mass of 0.3271 g, give 0.8055g Ca3(PO4)2. Report the % composition and the empirical formula of this compound.

5. A piece of nickel foil, 0.550 mm thick, 1.25 cm width and 1.00cm long, is allowed to react with fluorine, F2 to give a nickelfluoride. Density of nickel is 8.908 g/cm3. How many moles ofnickel foil were used? If you isolated 1.261 g of nickel fluoride,what is its formula?

Fluoridation is the process of adding fluorine compounds to drinking water to help fight tooth decay. A concentration of

1 ppm

of fluorine is sufficient for the purpose (1 ppm means one part per million, or 1 g of fluorine per 1 million g of water). The compound normally chosen for fluoridation is sodium fluoride, which is also added to some toothpastes.

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 175.0 gallons. (Sodium fluoride is 45.0 percent fluorine by mass. 1 gallon =

3.785 L

; 1 ton =

2000 lb

;

1 lb = 453.6 g

; density of water = 1.0 g/mL) Enter your answer in scientific notation.
