Suppose the half life of a isotope is 30 seconds and you have 10 grams to start with. how much will you have after one minute a. 5 grams b.3grams c. 2.5grams

The half life of a isotope is 30 seconds, and you have 10 grams to start with, after one minuet, you will have;

C. 2.5 Grams

t0 = 10g  

t30 = 5g Half-life 1  

t60 = 2.5g Half-life 2

Half-life means that as every half-life period passes, you have half of the isotope left, compared to what was there from the beginning.
