6.023 × individual carbon atoms are there in one mole of carbon.
Mass of a 1 atom= 12 amu
1 amu = 1.66 × gm
∴ 12 amu =1.99 × gm
∴Mass of a 1 atom=1.99 × gm
Mass of C in 1 mole = 12 gm
∴Total number of atoms of carbons in 1 mole = 12 ÷ 1.99 ×
∴Total number of atoms of carbons in 1 mole= 6.023 × atoms
6.023 × individual carbon atoms are there in one mole of carbon.
The number 6.023 × is known as Avogadro's number, which represents the number of individual atoms present in a one mole of substance with respect to atoms.

Answer:
The particles start moving faster and expand making the ball expand.
Explanation:
Data Given:
Moles = n = 3.91 mol
Pressure = P = 5.35 atm
Temperature = T = 323 K
Volume = V = ?
Formula used: Ideal Gas Equation is used,
P V = n R T
Solving for V,
V = n R T / P
Putting Values,
V = (3.91 mol × 0.0825 atm.L.mol⁻¹.K⁻¹ × 323 K) ÷ 5.35 atm
V = 19.36 L
