    Answer:

    100mg are in your system at 3pm

    Explanation:

    Half-life is the time necessary to decrease the initial amount of a substance in the half.

    At 12:00pm, the amount of aspirin is 800mg

    As half-life is 1h,

    at 1:00pm, the amount of aspirin is 800mg/2 = 400mg

    At 2:00pm, 400mg/2 = 200mg

    At 3:00pm, 200mg/2 =

    100mg are in your system at 3pm
