Problem

Liquid nitrogen is obtained from liquefied air and is used industrially to prepare frozen foods. It boils at 77.36 K. At the boiling point, the density of the liquid is 809 g/L and that of the gas is 4.566 g/L. How many liters of liquid nitrogen are produced when 895.0 L of nitrogen gas is liquefied at 77.36 K?

Solution

When N2 undergo phase change, it doesn’t change of composition. It’s still the same number of atoms and molecules. The mass of N2 doesn’t change when its phase changes

Therefore, we can solve this problem using the following steps:
