The half-life of a radioactive substance is the average amount of time it takes for half of its atoms to disentegrate. suppose you started with 200 grams of a substance with a half-life of 3 minutes. how may minutes have passed if 25 grams now remain? explain your reasoning.
Answers: 1
the final amount of the substance 
is the initial amount of the substance 
is the time 
is the half life
, 
, and 
. Lets replace those values in our formula:
