Aluminum chlorate ionizes as follows,
1 mol Aluminum chlorate ionizes to give 1 mole Aluminum ion and 3 moles of chlorate ion. Each mole aluminum ion has 4 * 3 = 12 moles of Oxygen atom.
Moles of = 0.08157 mol
a) Moles of =
b)Moles of
c) Moles of O atom =
The formula is simple.
Kinetic energy = Photon energy - Binding energy
In some places, binding energy is also called work function.
So, Photon energy =
=
(Here we multiply lambda by 10^(-9) to change nm to m)
=
J
Change it to ev from Joule (J)
so, Photon energy =
J =
= 7.8 eV
Now, KE = 7.8 - 3.31 = 4.57 eV
Done !!!
Mass of the substance = 360 gm
Volume of the substance = 7.5 cm^3
Now we know that
Density = Mass/Volume
= 360/7.5 gm/cm^3
= 48 gm/cm^3
So the density of the substance given in the question is 48 gm/cm^3.
. I hope that you have
understood the procedure by which the density of any substance can be easily
determined and also got the answer you were looking for. By following this
method you can easily determine the density of any substance without requiring
any help.

Based on nuclear stability, the symbol for the most likely product nuclide obtained when nitrogen-13 undergoes decay is coming from the following equation:
₇N¹³ → Positron₊₁⁰ + ₆C¹³
So the correct answer will be ₆C¹³
