The radioactive isotope of lead, Pb-209, decays at a rate proportional to the amount present at time t and has a half-life of 3.3 hours. If 1 gram of this isotope is present initially, how long will it take for 41% of the lead to decay? Type your answer in hours in the space provided below. Round your answer to two decimal places.
