The radioactive isotope technetium-99 in an excited state ( 9943tcm or tc-99m) can be used in medicine to determine a patient's blood volume. tc-99m emits gamma-rays and has a half-life t1/2 = 6.0h. a sample of tc-99m of mass 7.7x10-14kg is injected into the patient's circulatory system. 1.0 h after the injection, 20 cm³ of blood is taken from the patient. the activity of this sample is measured to be 55 kbq. calculate the patient's blood volume. show with explanations.
