1- An injection containing 10.0pg 10 5 B was injected into a patient suffering from a brain tumor. The patient was irradiated by a neutron gun at the site of the tumor. Calculate the amount of energy released in megaelectronvolts given that 931 MeV is released for each 1 amu mass defect. To calculate the energy released, consider the isotopic masses as follows:
Element or particle = Isotopic mass (amu):10 / 5 B = 10.0129neutron= 1.00867 3 Li = 7.0160alpha particle = 4.0026
Express your answer in megaelectronvolts to three significant figures.
