linen scrolls contain 80.9% of Carbon-14. how old are the scrolls if the half-life for deacy is 5.73X10^3??


plz tell me what type of equation to use.

  • chemistry math -

    ln(M/Mo) = -kt

    ln = natural log
    M = mass left (not needed)
    Mo = original mass (not needed)
    (M/Mo) = 0.809
    k = 0.693/T(half)
    T(half) = 5.73X10^3 years.
