What volume would 3.01•1023 molecules of oxygen gas occupy at stp?

11, 2 dm3 because one mole of a gas at STP occupies 22.4 dm3. And the number of molecules is half that of Avogadro's molar number therefore resulting in half of molar volume being occupied

Mitochondria is the cell organelle that produced the energy that is needed in the body system in form of atp, that is why it is called the power house of the cell. energy is needed by the living organisms to carry out the activities which sustain life.  if the mitochondria is destroyed atp will not be produced. if the mitochondria is destroyed, energy production will stop and the affected living organism will not have the energy to carry out the necessary life processes; this will lead to the death of the organism.

Can you put the picture?
