A radioactive element is known to decay at a rate proportional to its present mass. Initially, there is 0.0675 grams of the element. Three hours later, the remaining mass is 85% of its original mass. a. Compute the mass(in milligrams) of the element after 3.5 hours. Determine the time at which the element has decayed to one half of its initial mass.
