Answer:
541.74× 10²³ atoms of C
Explanation:
Given data:
Number of moles of carbon = 89.96 mol
Number of atoms = ?
Solution:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ atoms
89.96 mol × 6.022 × 10²³ atoms of C / 1mol
541.74× 10²³ atoms of C
