5. Carbon-11, used in medical imaging, has a half-life of 20.4 min. The carbon-11 nuclides are formed and the carbon atoms are then incorporated into an appropriate compound. The resulting sample is injected into a patient and the medical image obtained. If the entire process takes five half-lives, what percentage of the carbon-11 remains at this time?
