    Answer:

    Average Density = 1.07 g/cm³

    Explanation:

    The average density of the whole mixture is given by the following formula:

    Average\ Density = \frac{mass\ of\ whole\ mixture}{volume\ of\ whole\ mixture}

    where,

    volume of whole mixture = volume of water + volume of acid

    volume of whole mixture = 100 cm³ + 50 cm³ = 150cm³

    mass of whole mixture = mass of water + mass of acid

    mass of whole mixture = (volume of water)(density of water) + (volume of acid)(density of acid)

    mass of whole mixture = (100 cm³)(1 g/cm³) + (50 cm³)(1.2 g/cm³)

    mass of whole mixture = 160 g

    Therefore,

    Average\ Density = \frac{160\ g}{150\ cm^3}

    Average Density = 1.07 g/cm³
