A 1.50 liter tank filled with helium at 125 atm
is used to fill balloons. The pressure in each
balloon is 950 torr and the volume of each
balloon is 1.20 liters. How many balloons can
be filled?
Answer in units of balloons

Use PV = nRT and solve for n. Then determine n it takes to fill each balloon.
Then # balloons x (mol/baloon) = total n and solve for # balloons.
