Question

How many molecules of oxygen are in 3.0 moles of oxygen?

Answer 1

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

18.066× 10²³ molecules
