Answer:
After 3 half lives 12.5 g of C-14 left
Explanation:
Given data:
Mass of C-14 = 100 g
After 3 half lives mass left = ?
Solution:
At time zero = 100 g
At first half life = 100 g/2 = 50 g
At second half life = 50 g/ 2 = 25 g
At third half life = 25 g/2 = 12.5 g
Thus, after 3 half lives 12.5 g of C-14 left.
