Question

Density of water is 1 g/mL. The concentration of water in mol/litre is

Answer 1

Answer:

the density of water is 1gm/ml then weight of water present in one litre of water is 1000 grams.

So number of moles will be 1000/18 moles which are equal to 55.55 moles.

Definition of molarity is the number of moles of solute present in one litre of solvent.

Here the number of moles in one litre is 55.55.

So molarity of pure water is 55.55M
