Question

Calculate the number of water molecules and number of oxygen and hydrogen atoms in a drop of water containing 0.03 mole of water

Answer 1

Number of water molecules in 0.03 mol of water = 0.03 x 6.022 x 1023 = 1.8 x 1022 molecules of water. 1 water molecule(H2O) contain 1 oxygen atoms. So, number of oxygen atoms in 0.03 mole of water = 0.03 x 6.022 x 1023 = 1.8 x 1022 atoms of oxygen. 1 water molecule(H2O) contain 2 hydrogen atoms. So, number of hydrogen atoms in 0.03 mole of water = 2 x 0.03 x 6.022 x 1023 = 3.6 x 1022 atoms of hydrogen....

Answer 2

Answer:

Number of water molecules in 0.03 mol of water = 0.03 x 6.023 x 1023 = 1.8069 x 1022molecules of water.

1 water molecule(H2O) contain 1 oxygen atoms.

So, number of oxygen atoms in 0.03 mole of water = 0.03 x 6.023 x 1023 = 1.8069x 1022atoms of oxygen.

1 water molecule(H2O) contain 2 hydrogen atoms.

So, number of hydrogen atoms in 0.03 mole of water = 2 x 0.03 x 6.023 x 1023 = 3.6138 x 1022 atoms of hydrogen
