Question

volume occupied by 7 molecule of the water is

Answer 1

volume of one molecule of water - The number of moles in 1 litre = 1000 / 18.02 = 55.5 moles. 1 mole of water = 6.022 x 10^23 molecules of water, So 55.5 moles of water = 55.5 x 6.022 x 10^23 = 3.34 x 10^25 molecules of water. The gram molecular mass of water is 18.02. Thus volume occupied by 1 H2O mlecule is ​2.99 ​×10-23 ml.
