Question

Calculat the number of water molecules and number of oxygen and hydrogen atom in a drop of water containing 0.03 mol of water​

Answer 1

Explanation:

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.
