Question

A balloon contains 4 moles of an ideal gas with a volume of 5l. If an additional 8 moles of the gas are added at constant pressure and temperature. What will be the final volume of the balloon?

Answer 1

Answer:

A balloon contains 4 moles of an ideal gas with a volume of 5l. If an additional 8 moles of the gas are added at constant pressure and temperature.The final volume of the balloon will be 15 L

Explanation:

Avogadro’s law states that the total number of atoms/molecules of a gas (i.e. the amount of gaseous substance) is directly proportional to the volume occupied by the gas at constant temperature and pressure.

So N1/V1=N2/V2

where N represent moles

  and V represent volume

4/5=12/V

v=15 L
