Question

volume occupied by one molecule of water (density=1g cm^-3)

Answer 1

hope it help to u


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 molecule is ​2.99 ​×10-23 ml.
