a 1.69 mol sample of freon gas was placed in a balloon. adding 3.50 mol of freon gas to the balloon increased its volume to 32.3 l. what was the initial volume of the balloon?



Answer :

The initial volume of the balloon when a 1.69 mol sample of freon gas was placed in a balloon. adding 3.50 mol of freon gas to the balloon increased its volume to 32.3 l is 17.5 L

The ideal gas equation is given as

PV=nRT

where

P

is the pressure,

V is the volume,

R=0.0821L

For the constant value of P and T ratio is constant

V1/n1=V2/n2

Substituting the values, we get

V1/1.73=32.3/1.69+1.50

V1=17.5 L

  • An ideal gas follows the ideal gas equation.
  • It is also called the equation of state.
