calculate number of water molecules and number of oxygen and hydrogen atom in a drop of water containing 0.05 mole of water ​

molecules of water

atoms of hydrogen

atoms of oxygen

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number of particles.

1 mole of water contains = molecules of water

Thus 0.05 moles of water contain = molecules of water

Now , 1 molecule of water contains= 2 atoms of hydrogen

molecules of water contain = atoms of hydrogen

Now , 1 molecule of water contains = 1 atom of oxygen

molecules of water contain = atoms of oxygen  

what are the two models

explanation:

there is none because earth is stationary and flat.
