    Answer is: 31,45%.

    mrs₁ (C₉H₁₆O₄ - azelaic acid) = 12g.

    mr ₂ (C₉H₁₆O₄) = 50g.

    ω₂ (C₉H₁₆O₄) = 15% = 0,15.

    mrs₂ (C₉H₁₆O₄) = mr₂·ω₂ = 50g·0,15 = 7,5g.

    mrs₃ (C₉H₁₆O₄) = mrs₁ + mr₂ = 12g + 7,5g = 19,5g.

    mr₃ = mr₂ + mr₂ = 50g + 12g = 62g.

    ω₃ = mrs₃:mr₃ = 19,5g : 62g = 31,45% = 0,3145.
