Tooth enamel consists of hydroxyapatite, Ca5(PO4)3(OH). This substance is converted to the more decay-resistant fluorapatite, Ca5(PO4)3F, by treatment with tin(II) fluoride, SnF2. Products of this reaction are tin(II) oxide and water. What mass of hydroxyapatite can be converted to fluorapatite by reaction with 0.100g of tin(II) fluoride?
