I need help with the following problem: A fabric remnant from a burial site had a 14 C:12 C ratio of 0.838 of the original value. How old is the fabric? (half-life of 14 C = 5370 years)

  • Chemistry -

    Amountremaining=Originalamount*e^(-.692t/5370)

    .838=e^^-692t/5370)
    ln .838=-t/5370
    solve for t
