# Solution: A 12 Liter tank contains helium gas pressurized to 160 atm.How many 3-liter balloons could the 12 Liter helium tank fill?(Keep in mind that an "exhausted" helium tank is not empty. In other words, once the gas inside the tank reaches atmospheric pressure, it will no longer be able to fill balloons.)

###### Problem

A 12 Liter tank contains helium gas pressurized to 160 atm.

How many 3-liter balloons could the 12 Liter helium tank fill?

(Keep in mind that an "exhausted" helium tank is not empty. In other words, once the gas inside the tank reaches atmospheric pressure, it will no longer be able to fill balloons.)

###### Solution

Recall: The ideal gas law is given by the equation: PV = nRT

At constant temperature and moles of gas: The equation P1V1 = P2V2 is Boyle's Law, which states that the pressure of a certain amount of gas at a certain temperature is inversely proportional to its volume, i.e. the pressure decreases as volume increases. View Complete Written Solution
