A gas-filled balloon having a volume of 1.00 L at 1.2 atm and 25°C is allowed to rise to the stratosphere (about 30 km above the surface of Earth), where the temperature and pressure are -23°C and 3.00 10-3 atm, respectively. Calculate the final volume of the balloon.

The final volume of the balloon is 335.6 L

Explanation:

To calculate the final volume of the balloon, we use the equation given by combined gas law:

where,

= Initial pressure = 1.2 atm

= Final pressure = atm

= Initial volume = 1.00 L

= Final volume = ?

= Initial temperature =

= Final temperature =

Putting values in above equation, we get:

Hence, the final volume of the balloon is 335.6 L

the correct answer is answer a. a mixture

no other options make sense

hope this

have a great day : )
