Tin (11) fluoride, SnF2, is found in some toothpastes. Tin (II) fluoride is made by reacting solid tin with hydrogen fluoride according to the following BALANCED equation.
Sn (s) + 2 HF (g)-SnF₂ (s) + H₂ (8)
How many moles of tin (II) fluoride will be produced if 22.9 grams of hydrogen fluoride react?
