    Answer:0.102 milliliters is required

    Explanation:

    The easy way to obtain this is to take unit conversation very important as diphenhydramine has a molar mass of 255.355grams per mole and the concentration of the liquid diphenhydramine is 12.5 milligrams per 5 milliliters.

    We have to convert the molar mass into milligrams per mole by dividing by 1000 which yields 0.255355mg/mol then;

    Simplify the molar mass divided by the concentration of the liquid diphenhydramine;

    0.255355/12.5/5

    This equals 0.102 milliliters!
