question

It is given that masses of a proton and an electron are equal to 1.00728 and 0.000549 u, respectively. A fluorine atom contains 9 protons and 9 electrons. What mass frac-tion of the fluorine atom is contained in the nucleus? De-termine the fraction of the atomic volume, where r = 0.64°A occupied by the nucleus using the following equation: r^1 = (1.5 10^-15m) A^1/3. where r^1 = radius of a nucleus A = mass number.
