✔ 最佳答案
In 100 g of SnF we have
75.75g of Sn = 75.7/ 118.7 moles of Sn = 0.637


24.25 g of F = 24.5 /19 moles of F= 1.289

ratio of the 2 moles is found by dividing by the smallest number

.637

So moles of Sn : F = 1:2

empirical formula

SnF2

Over twenty-five studies show fluoride lowers the intelligence of children. Trying to create a moron, are you? Bucket medication is unscientific. So is prescribing even more fluoride without first checking the content of fluoride in the body, (i.e. hair, blood, urine). Did the dentist check the levels of fluoride already in your child before prescribing the super fluoride toothpaste? Fluoride is absorbed through the tissues of the mouth. You don't have to swallow it to ingest it. If you live in America, fluoride is now in all foods, beverages, pollution, etc... everything but distilled water. It isn't required to be labeled on containers. It's absorbed through the skin when showering or bathing. Now calculate your daily dose.
