How much tin II fluoride will be made when reacting 45.0 grams of tin with an excess of hydrofluoric acid if the percent yield for the reaction is 60% Sn + HF = SnF2 + H2

Mass of SnF₂ produced : 35.634 g

Reaction

Sn+2HF⇒SnF₂+H₂

mol Sn (Ar 118.710 g/mol) :

mol SnF₂ = mol Sn = 0.379

mass SnF₂ (MW=156.69 g/mol) :

⇒theoretical
