Question

4. One mole of oxygen contains 6.02 x 102 molecules. How many oxygen molecules are in

5.55 moles of oxygen gas?|

Answer 1

3.34x10²⁴ molecules of oxygen

Step-by-step explanation:

1 Mole of particles of any kind of gases or particles are always 6.022x10²³.

1 mole of electrons are 6.022x10²³ electrons

1 mole of any gas are 6.022x10²³ molecules

1 mole of oxygen are 6.022x10²³ molecules. Thus, 5.55 moles are:

3.34x10²⁴ molecules of oxygen
