If the density of liquid N2 is D then a volume V will contain
D*V/28 moles
and each mole occupies about 25 litres at 25 °C and 1 bar.
At the normal boiling temperature of N2 of 77 K the volume would be considerably less by a factor of 77/298.

liquid having specific volume and gas has no specific volume
that depends on if fill one litre liquid in 2 litre capacity cylinder it occupies only one litre capacity,but unlike liquids gases expand and is filled whole cylinder if it is closed otherwise it escapes

liquids cannot be compressed or expanded unlike gases. Gases have a different volume at a different temperature.

you must determine condition , for example temperature , pressure etc
