Question

For $22.4$ liters of water vapour at NTP when condensed to water occupies an approximate volume of:
A) $18litre$
B) $1litre$
C) $1ml$
D) $18ml$

Answer 1

We need to remember that the mass per unit volume is defined as the density of a material. It's an estimation of how firmly matter is pressed together. The thickness of a substance can be clarified as the connection between the mass of the substance and volume it takes up.

Complete step by step answer:
We know that the molar mass of one mole of water vapor is $18gm$ .
It is known that,
Mass of one mole of water vapor=mass of one mole of water
Given,
The density of water is $1g/ml$
Now, one can calculate the volume by rearranging the density formula,
$Volume = \dfrac{{mass}}{{density}}$
Now we can substitute the known values we get,
$Volume = \dfrac{{18g}}{{1g/ml}}$
On simplification we get,
$Volume = 18ml$
Thus the correct answer is D.

Note:
As we know that there are a few variables which can influence the thickness of a substance. A few components which influence the thickness of water are given in the focuses beneath.
The thickness of water is around roughly 1 gram/cubic centimeter.
It is temperature-subordinate, yet this connection is supposed to be non-straight and furthermore it is unimodal in nature as opposed to monotonic.
At the point when it is cooled from the room temperature, the fluid water will in general turn out to be progressively thick, similarly as with other sorts of substances, however around at about $4^\circ C$ , unadulterated water is said to arrive at its greatest thickness.
As it gets cooled further, it will in general extend and turn out to be less thick. This sort of irregular negative warm extension is identified with solid, intermolecular powers, direction ward, or cooperations and it is seen as liquid silica.
