# Solution: A 16.0 -L tank is filled with helium gas at a pressure of 105 atm .How many balloons (each 2.00 L) can be inflated to a pressure of 1.00 atm, assuming that the temperature remains constant and that the tank cannot be emptied below 1.00 atm?

###### Problem

A 16.0 -L tank is filled with helium gas at a pressure of 105 atm .

How many balloons (each 2.00 L) can be inflated to a pressure of 1.00 atm, assuming that the temperature remains constant and that the tank cannot be emptied below 1.00 atm?

###### Solution

We're being asked to determine the number of balloons that can be inflated to a pressure of 1.00 atm

Recall that the ideal gas law is:

$\overline{){\mathbf{PV}}{\mathbf{=}}{\mathbf{nRT}}}$

The pressure and volume of a gas are related to the number of moles, gas constant and temperatureThe value nRT is constant
