Answer: 6.0225X10^23
Explanation:
We know that Carbon has atomic mass equal to 12g, I. E. One mole of carbon atom weighs 12g. We know that one mole of any substance contains 6.0225X10^23 particles(atoms, molecules, ions, etc.). Thus 12g of Carbon contains 6.0225X10^23 atoms of Carbon.
11.44 × 10²³ atoms are present in 23.0 g of carbon.
Number of atoms = Number of moles × Avogadro's Number
Number of moles = [tex]\frac{\text{Given Mass}}{\text{Molar Mass}}[/tex]
Avogadro's number is the number of particles in one mole of substance. 6.022 × 10²³ is known as Avogadro's constant / Avogadro's number.
Avogadro's number = 6.022 × 10²³
First we have to find the number of moles
Number of moles = [tex]\frac{\text{Given Mass}}{\text{Molar Mass}}[/tex]
= [tex]\frac{23}{12}[/tex]
= 1.9 moles
Now put the values in above formula to find the number of atoms
Number of atoms = Number of moles × Avogadro's Number
= 1.9 × 6.022 × 10²³
= 11.44 × 10²³ atoms
Thus, we can say that 11.44 × 10²³ atoms are present in 23.0 g of carbon.
