A mixture contained no fluorine compound except methyl fluoroacetate, FCH2COOCH3 (molar mass = 92.1g/mol). While chemically treated, all the fluorine was converted to CaF2 (molar mass = 78.1 g/mol). The mass of CaF2 obtained was 12.1 g. Define the mass of methyl fluoro acetate in the original mixture.
92.0g
28.5g
24.2g
