1.50 liters 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 is 1.20 liters. How many ballons can be filled?

I would use PV = nRT and solve for n for the 1.5 L tank at 125 atm. You aren't given T so just make up a convenient T and use it in this and the next calcn.

Then use PV = nRT again for the balloons to determine moles for each balloon, then divide the larger number by the smaller number to find the number of balloons that can be filled.
