The half-life of a radioactive substance is 8.93 years. If 6 grams of the substance is present now, how much will be present in 15 years? Round to the nearest hundredth of a gram. Recall: Q(t) = Qoekt. Use the model Q(t) = Qoe-0.000121€ for radiocarbon dating. If a petrified bone is found to have 82% of the carbon-14 remaining, how old is the bone? Round to the nearest year.
