A mixture contained no fluorine compound except methyl fluoroacetate,FCH₂COOCH₃ (molar mass = 92.07 g/mol).When chemically treated,all the fluorine was converted to CaF₂ (molar mass = 78.08 g/mol).The mass of CaF₂obtained was 35.8 g.Find the mass of methyl fluoroacetate in the original mixture.

Question

Quizplus · Accepted Answer

The molar ratio of methyl fluoroacetate to CaF2 is 1:1. The moles of CaF2 are 35.8 g / 78.08 g/mol = 0.458 moles. Therefore, the mass of methyl fluoroacetate is 0.458 moles * 92.07 g/mol = 42.2 g.
