Answer:
0.86 moles of CO₂
Step-by-step explanation:
Given data:
Number of atoms of CO₂ = 5.2×10²³ atom
Number of moles = ?
Solution:
Avogadro number:
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
5.2×10²³ atom× 1 mol / 6.022 × 10²³ atoms
0.86 mol
