The number of atoms in the 6 grams of carbon is equal to 1.506 × 10²³.
The Avogadro number is the proportionality factor which is the number of particles such as atoms, molecules, or ions in one mole of a substance.
Avogadro's number possesses a numeric value of 6.022 × 10²³ reciprocal moles. Avogadro's constant is named by Stanislao Cannizzaro after the scientist Amedeo Avogadro.
Given, the mass of the carbon in sample = 6 g
The number of atoms of one mole of carbon = 6.022 × 10²³
The atomic mass of one mole of carbon = 12 g
It means 12 g of the carbon has atoms = 6.022 × 10²³ carbon atoms
Then 6 grams of carbon will have atoms = (6/12) × 6.022 × 10²³
= 3.011 × 10²³ carbon atoms
Therefore, the atoms of carbon in 6 g of sample of carbon are 3.011 × 10²³ atoms.

Answer:
In the orbitals of the atom
Answer: the reactant left in excess is H₂, and the amount of excess H₂ is 4.5 moles - 3 moles = 1.5 moles.
Explanation: Moles of N₂ = mass of N₂ / molar mass of N₂
Moles of N₂ = 56 g / 28 g/mol = 2 moles
Moles of H₂ = mass of H₂ / molar mass of H₂
Moles of H₂ = 9 g / 2 g/mol = 4.5 moles
