Taking into account the ideal gas law, the pressure is 2.52 atm.
An ideal gas is a theoretical gas that is considered to be composed of randomly moving point particles that do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.
The pressure, P, the temperature, T, and the volume, V, of an ideal gas are related by a simple formula called the ideal gas law. This equation relates the three variables if the amount of substance, number of moles n, remains constant. The universal constant of ideal gases R has the same value for all gaseous substances. The numerical value of R will depend on the units in which the other properties are worked.
P×V = n×R×T
In this case, you know:
- P=?
- V= 500 L
- n= 52.1 moles
- R= 0.082
- T= 22 C= 295 K (being 0 C=273 K)
Replacing in the ideal gas law:
P×500 L = 52.1 moles ×0.082 ×295 K
Solving:
P= (52.1 moles ×0.082 ×295 K)÷ 500 L
<u><em>P= 2.52 atm</em></u>
Finally, the pressure is 2.52 atm.

Answer:
This question is incomplete without the table
Explanation:
The missing table is attached to this answer.
There are three subatomic particles found in an atom; protons, neutrons and electrons. The properties of the subatomic particles will be classified under the following subheadings (which are the empty columns/boxes in the attachment)
SYMBOL
The symbol of proton is "p⁺", the symbol of neutron is "n⁰" and the symbol of electron is "e⁻".
CHARGE
Looking at the symbol of the subatomic particles, one can guess the charge of each of the particles from the superscript.
Protons are positively charged, electrons are negatively charged while neutrons have no charge/electrically neutral.
The relative charge of proton is +1 while it's absolute charge is +1.60218 × 10⁻¹⁹
The charge of a proton was first determined by Ernest Rutherford using the gold-foil experiment
The relative charge of electron is -1 while it's absolute charge is -1.60218 × 10⁻¹⁹
The charge of an electron was first determined by R. Milikan using the oil-drop experiment
The relative charge and absolute charge of neutron is 0
The charge of a neutron was first determined by (or credited to) James Chadwick.
MASS
The relative mass (amu) of proton is 1.00727 while that of neutron is 1.00866. The relative mass (amu) of an electron is 0.00054858 while it's absolute mass (g) is 9.10939 × 10⁻²⁴.
The mass of an electron was first measured by J. J. Thomson.
The mass of a proton was first measured by (or credited to) Ernest Rutherford.
The mass of a neutron was first measured by James Chadwick.
LOCATION
The protons and neutrons <u>are located inside the nucleus</u> which is found in the centre of an atom while the electron(s)<u> is/are found outside the nucleus but within the atom</u>.
