How many molecules are equal to 3.52 moles of oxygen difluoride?

3.52 moles are equal to 21.2 ×10²³ molecules

Explanation:

Given data:

Number of moles of oxygen fluoride = 3.52 mol

Number of molecules = ?

Solution:

The given problem will solve by using Avogadro number.

1 mole contain 6.022×10²³ molecules

3.52 mol ×6.022×10²³ molecules / 1 mol

21.2 ×10²³ molecules

Thus, 3.52 moles are equal to 21.2 ×10²³ molecules .
