Radioactive Dating, calculating age?

  1. Apr 12, 2012 #1
    1. The problem statement, all variables and given/known data
    The age of the dead sea scrolls was measured using radiocarbon dating. If the measurement gives a ratio of 0.78 for the ratio of the activity in the sample to the activity in a sample of corresponding live material of similar mass, calculate the age of the scrolls.


    2. Relevant equations
    N=N°e^λt λ=ln2/t^1/2


    Can anybody shed some light?

    thanks,
