Answer:
18.066× 10²³ molecules
Explanation:
Given data:
Number of moles of oxygen = 3.0 mol
Number of molecules = ?
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 molecules
3 mol × 6.022 × 10²³ molecules / 1 mol
There are 18 moles of oxygen in 3.0 mole of glucose...
