At constant temperature and pressure, If the amount of gas increases to the given value, its volume also increases to 20.85L.
<h3>What is Avogadro's law?</h3>
Avogadro's law states that "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules."
It is expressed as;
V₁/n₁ = V₂/n₂
Given the data in the question;
- Initial amount of gas n₁ = 2moles
- Initial volume v₁ = 13.9L
- Final amount of gas n₁ = 3moles
V₁/n₁ = V₂/n₂
V₁n₂ = V₂n₁
V₂ = V₁n₂ / n₁
V₂ = (13.9L × 3moles) / 2moles
V₂ = 41.7molL / 2mol
V₂ = 20.85L
Therefore, at constant temperature and pressure, If the amount of gas increases to the given value, its volume also increases to 20.85L.

Answer: The volume of tank is 17.5 L.
Explanation:
Given: Mass of methane = 173 g
Pressure = 15.1 atm
Temperature = 298 K
Molar mass of methane is 16.04 g/mol.
Therefore, moles of methane are calculated as follows.
Now, ideal gas equation is used to calculate the volume as follows.
PV = nRT
where,
P = pressure
V = volume
n = no. of moles
R = gas constant = 0.0821 L atm/mol K
T = temperature
Substitute the values into above formula as follows.
Thus, we can conclude that volume of the tank is 17.5 L.

Explanation:
From the given table, we can simply complete the given table by identifying the meaning of each column header.
- Number of protons in an atom is the number of positively charged particles in the nucleus of the atom. Protons are positively charged particles in an atom.
- The number of neutrons are the number of neutrally charged particles occupying the nucleus of an atom.
- Atomic number is another term for the number of protons in an atom.
- Mass number is the sum of protons and neutron in an atom.
- The symbol of an element is used represent a particular atom.
Mass number = number of protons + number of neutrons
Atomic number = number of protons = number of electrons in atoms.
