A balloon i filled to a volume of 1. 50 L with 2. 50 mole of ga at 25 °C. With preure and temperature held contant, what will be the volume of the balloon if 1. 40 mole of ga are added?

The equation of state for a fictitious perfect gas is known as the ideal gas law, sometimes known as the generic gas equation. Although it has some restrictions, it is a good approximation of the behaviour of numerous gases under various circumstances.
An amount of gas's pressure, volume, and temperature all affect its condition. These are simply related in two ways by the equation as it is used today. The kelvin is the proper SI unit to use for expressing the temperature in the equation of state because it is an absolute temperature.

The properties of an ideal gas are all summarized in one formula of the form:

pV = nRT

p is the pressure of the gas

V is the volume of the gas

n is the amount of substance

R is the ideal gas constant

T is the temperature of the gas

Pressure in the balloon :

p = nRT/v

= 2.5 mole *25 C *8.3145 / 1. 50L

= 4131595 pa

New Volume of balloon :

v = nRT/p

= 3.9 mole * 25 C* 8.3145 / 4131595 pa

= 2.34 L

The volume of balloon is 2.34 L.
