Question

The volume of one litre. Water upon vapourisation at stp is nearly

Answer 1

The molarity of 1 lire water is 55.5 ie no. of moles of water in 1 litre of it is 55.5 , there fore volume occupied by vapours ...

Answer 2

↪Ideal Gas↩

We already know the value of the density of water which is 1 g/mL.

So, we can find the amount of the moles of water present in 1000ml.

Hence, 1000 mL or 1 L of water will have = 1000/18 moles = 55.56 moles.

This 55.56 is the molarity of the water.

As in the given question it is asked about STP hence we get that:

The volume of 1 mole of water on vapourization or of any gas is 22.4L.

So, know we know that the volume of 55.56 moles of water is :-

55.56 × 22.4 L= 1244.44L .
