    If you have 500 grams of isotopes, how many would you have after 54 minutes?

    Can you explain in more detail? Istopes decay at different rates.

    It depends on the half life of the isotope. If the half life is 54 minutes, then after 54 minutes the original 500 grams would have decayed to leave only half the original amount, or 250 grams of the isotope.
