Assuming the density of water to be 1 g/ml, calcu

ANSWER

The density of water is approximately 1g/ml.

Thus, 1g of water occupy volume  = 1 ml

The molar mass of water = 18 g/mol

Number of moles of water in 1g = 181 moles = 0.055 moles H2O

Now 18 g water contain = 6.022 × 1023 moleculesH2O

Thus 1 g water will have =186.022×1023 molecules H2O = 0.334  × 1023 molecules H2O

This shows that 

 0.334  ×1023 molecules H2O  will occupy volume = 1 ml
