Hi, I need help with this half-life problem: Phosphorus-32 has a half-life of 14.0 days. Starting with 8.00g of 32-P, how many grams will remain after 42.0days?

42.0days/14days = 3 half lives... you see so that means u started with 8 grams first half life means u cut it in half. 4 gs left. then another half life cut that in half 2gs left then another half life cuts that in half. After three half lifes u only have 1 g left.
