Five Radioactivity and Nuclear Chemistry Questions

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 = 10.0129
neutron= 1.0086
7 3 Li = 7.0160
alpha particle = 4.0026

Express your answer in megaelectronvolts to three significant figures.

2- Calculate the mass defect of the fluorine nucleus 19 /9 F. The mass of neutral 19 / 9 F is equal to 18.998403 atomic mass units. Express your answer in atomic mass units to four significant figures and u units

3- Calculate the binding energy E/ B of the fluorine nucleus 19 / 9 F .Express your answer in millions of electron volts to four significant figures and MeV units.

4-Calculate the binding energy per nucleon of the fluorine nucleus 19/ 9 F .Express your answer in millions of electron volts to four significant figures and MeV / nucleon units.

5- Calculate the mass defect of the helium nucleus 4 /2 He. The mass of neutral 4 /2 He is given by M/ He =4.002603u .Express your answer in atomic mass units to four significant figures and in u units.
