Answer:
Step-by-step explanation:
Half life is the time taken by a radioactive substance to reduce of half of its original size
If the half life of radium is 1600, this means that the original radioactive substance N0 have reduced to N0/2 after 1600 years
if we are given N0 = 1000grams
The amount of the substance that will remain after 1600 years will be N0/2 i.e 1000/2 = 500g
<em>Hence 500 grams of radium will be left after 600years</em>
The range is just the distance between the biggest number
and the smallest one.
The biggest number on that list is 350 .
The smallest number on that list is 75 .
The range is from 75 to 350, or a distance of 275 .
