In small amounts, the fluoride ion (often consumed as NaF) prevents tooth decay. According to the American Dental Association, an adult female should consume 3.0 mg of fluorine per day. Calculate the amount of sodium fluoride (45.24% F) that a woman should consume to get the recommended amount of fluorine.
Solution 77P
Given that 100 grams of NaF contains 45.24 grams of F
1 gram of F will be contained in 100/45.24 grams of NaF
4.8 grams of F will be contained in 6.631 grams of NaF
Thus the amount of NaF a woman should consume to get the recommended amount of fluorine.
will be 6.63 grams
