Radioactive materials are often used in biological studies. A radiation biologist studies the rate of decomposition of a certain substance and obtains the following data:Time(days)04.08.012.016.0Mass (?g)26.0017.7112.068.225.60Determine the rate constant in units of days-1.How many micrograms will remain after 39 days?
