The value is 
Explanation:
From the question we are told that
The volume of liquid nitrogen is 
The density of nitrogen at gaseous form is 
= The dry air at sea level
Generally the density of nitrogen at liquid form is
And this is mathematically represented as
=> 
Now the density of gaseous nitrogen is
=> 
Given that the mass is constant
=>
