Phosphorus-32 is used in biochemical studies to follow the pathway taken by metabolites. Its half-life is 14.3 days. A vial containing 10.0 of P-32 is accidentally spilled into a sink. (a) How long will it take P-32 in the drain to exhibit 68% of its original activity? (b) How many atoms of P-32 remain in the sink after 755 days?
