To answer this item, we are to assume that the given gas behaves ideally such that it can follow one of the simplified ideal gas law as written below,
                  P₁V₁ = P₂V₂
where P is the pressure and V is the volume. 
Substituting the known values, while V₂ is unknown,
                 (100 atm)(10 L) = (1 atm)(V₂)
The value of V₂ is calculated to be equal to 1000 L. 
The number of balloons that can be filled is as calculated.
                      n = (1000 L) / (1 L / balloon)
                               n = 1000
