    Answer:

    2.34 %

    Explanation:

    Since the density of the Jello, ρ = 1.14 g/mL and ρ = m/v where m = mass of jello and v = volume of jello = 475 mL.

    So, m = ρv

    substituting the values of the variables into the equation, we have

    m = ρv

    m = 1.14 g/mL × 475 mL = 541.5 g

    Since we have 13 g of sugar in the jello, the total mass present is 13 g + 541.5 g = 554.5 g

    So, the percentage by mass of sugar present % m/m = mass of sugar present/total mass × 100 %

    = 13 g/554.5 g × 100 %

    = 0.0234 × 100 %

    = 2.34 %

    So, the percentage by mass of sugar present % m/m = 2.34 %
