A balloon filled with helium gas at 20°C occupies 2.91 L at 1.00 atm. The balloon is immersed in liquid nitrogen at -196°C, raising the pressure to 5.20 atm. What is the volume of the balloon in the liquid nitrogen?

0.147 liters  is the volume of the balloon in the liquid nitrogen.

Explanation:

Pressure of helium gas P1 = 1 atm

temperature T1 = 20 degrees or 293.15 K

volume V1 = 2.91 L

Pressure when immersed in liquid nitrogen = 5.20 atm

temperature T2 = -196 degrees 77.15 K

V2 = ?

Gas law for expansion of gases:

=

V2 =    equation 1

Putting the values in the equation:

V2 =

      = 0.147 Litre is the volume of the balloon immersed in liquid nitrogen.

hence V2 = 0.147 litres.

the correct name for the n3 ion is azide. azide is a polyatomic anion with a -1 charge and is written as n3 -1. it consists of three nitrogen atoms bonded together. hope i . let me know if you need anything else.
