    1.5

    Explanation:

    Data obtained from the question include:

    C (critical angle) = 41.8°

    n (refractive index od benzene) = ?

    Using the formula n = 1/sineC, the refractive index of benzene can be achieved as shown below:

    n = 1/sineC

    n = 1/sine 41.8°

    n = 1.5

    Therefore, the refractive index of benzene is 1.5
