Calc. the MM from decay and half life

  1. Jun 3, 2005 #1
    howdy,
    how can one determine molar mass when the half life and dacay rate (d/min) and mass of matter are known? im really puzzled. thanks for the help.

    Please post the exact question and your thoughts. As of now, there's insufficient data.

    Gokul: if the decay is defined as counts/minute there is enough data to solve the question :smile:

    Calculate number of atoms in the sample that shows known number of decays per minute. You know the number of atoms, you know number of moles. Ready.

    It would be appropriate to post the exact form of the question.

    True (if the decay rate and mass are the "initial decay rate" and the "initial mass").
