An initial amount of 100 g of the radioactive isotope protactinium-230 decays according to the following equation where t is in days. Q(t) = 100e−0.03984t How long before half of the initial amount has disintegrated? This time is called the half-life of this isotope. (Round your answer to one decimal place.)
