A sample of charcoal is found to have only 1/8th of Carbon-14. Half-life of Carbon-14 is 5730yrs, what is the age of the charcoal?

  • Chemistry -

    k = 0.693/t1/2
    Substitute and solve for k.

    ln(No/N) = kt
    Pick any convenient number for No, such as 100.
    Then N = 1/8 that or 12.5
    k = from above.
    Solve for t in years if half life is in years.
