The volume occupied by the given mol of helium gas at the given temperature and pressure is 91.6L.
The Ideal gas Law, also called the overall fuel equation, is the equation of kingdom of a hypothetical ideal gas. It is a superb approximation of the conduct of many gases below many situations, even though it has several limitations.
The precise gas regulation states that PV = NRT, wherein P is absolutely the pressure of a gasoline,volume V is the quantity it occupies, N is the quantity of atoms and molecules inside the fuel, and T is its absolute temperature.
Given;
Amount of helium n = 2.59 mole
Pressure p = 0.826 atm
Temperature T = 356 K
The volume of Helium = ?
PV = nRT
V = nRT/P
V = 2.59 mole * 0.826 atm * 356K/0.826
V = 75.6626/0.826
V = 91.6 L

Explanation:
The subatomic particles in any atom are made up of protons, neutrons and electrons in it.
Protons are the positively charged particles.
Neutrons do not carry any charges.
Together with protons, they occupy the nucleus.
Electrons are negatively charged particles.
In an atom of B - 11;
11 is the mass number
mass number = number of protons + number of neutrons.
Total subatomic particles = proton + neutrons + electrons
TSP = mass number + electrons
In B, the atomic number = 5 = number of electrons
TSP = 11 + 5 = 16
