    C5H10O5

    Explanation:

    The molecular formula is a multiple of the empirical formula. I. e

    Molecular formula = > [CH2O]n

    [CH2O]n = 150

    [12 + (2x1) + 16 ]n = 150

    30n = 150

    Divide both side by the coefficient of n i. e 30

    n = 150/30 = 5

    Molecular formula = > [CH2O]n

    Molecular formula = > [CH2O]5

    Molecular formula = > C5H10O5
