Given :

12.9 mol of Au.

To Find :

How many atoms are in 12.9 moles Au.

Solution :

We know, 1 mol of any element/molecules contains 6.022\times 10^{23}\ atoms/mol.

Number of atoms in 12.9 moles of Au is :

n = 12.9 \times 6.022\times 10^{23}\ atoms\\\\n = 7.77\times 10^{24}\ atoms

Therefore, number of atoms in 12.9 moles of Au is 7.77\times 10^{24}\ atoms.

Hence, this is the required solution.

Answer:

Ideal gas explains the property of gas that has no inter-molecular attractions irrespective of temperature and pressure.

<u>Explanation:</u>

  • Ideal gases assumes that the gases would experience no inter-molecular attraction and collision with other gases.
  • These gases are perfectly exhibiting elastic collision in nature.
  • The particle of gases moves slowly at lower temperature and the gases would become close when they exhibit high pressure.
  • The "closeness of the gas-particle" and "low-speed characteristics" are the important observations noted.
  • The inter-molecular forces deviate the property of gases from ideal gas behavior.
