Dry air is primarily composed of nitrogen. In a classroom demonstration, a physics instructor pours 3.6 L of liquid nitrogen into a beaker. After the nitrogen evaporates, how much volume does it occupy if its density is equal to that of the dry air at sea level

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

=>
