Step-by-step explanation:
To find the answer convert the amount kilograms you have to grams
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>
1.27 = 1 27/100

348 rounded to tens place = 350
348 rounded to hundreds place = 300 (possibly 400)
