Volume fraction =Mass  fractionSpecific  gravity= \frac{Mass\; fraction}{Specific\; gravity}

Mass fraction =Volume  fraction×Specific  gravity= Volume \;fraction \times Specific\; gravity

Mass fraction =0.8629×0.4040=0.3487= 0.8629 \times 0.4040 = 0.3487

Mole fraction =Mass  fractionMolecular  weight= \frac{Mass \;fraction}{Molecular\; weight}

Mole fraction =0.648759.00=0.0059= \frac{0.6487}{59.00}= 0.0059
