A mixture contained no fluorine compound except methyl fluoroacetate, FCH₂COOCH₃ (molar mass = 92.1 g/mol. When chemically treated, all the fluorine was converted to CaF₂ (molar mass = 78.1 g/mol). The mass of CaF₂ obtained was 12.1 A) 28.5 g B) 92.0 g C) 14.3 g D) 24.2 g E) 12.1 g

Question

Quizplus · Accepted Answer

The balanced chemical equation is:2 FCH₂COOCH₃ + Ca(OH)₂ → CaF₂ + (CH₃COO)₂Ca + 2 H₂OMoles of CaF₂ = 12.1 g / 78.1 g/mol = 0.155 molMoles of FCH₂COOCH₃ = 2 x 0.155 mol = 0.31 molMass of FCH₂COOCH₃ = 0.31 mol x 92.1 g/mol = 28.5 g
