The buoyancy force must equal the weight lifted. Let V be the volume.

g*[(He density)* V + 650 kg] = (Air density)*V*g

Cancel out the g's. Assume the outside air density correesponds to the same 1 atm and 0 C. He density is 4 kg/22.4 m^3 and the air density is 29/22.4 kg/m^3

0.179 V + 650 = 1.295 V

Solve for V (in cubic meters)

g*[(He density)*V+650+4600]=Air density *V*g

g= gravity= 9.8 N/Kg

Air Density= 1.29 Kg/m^3

He Density= 0.179 Kg/ m^3

Ballon Voulme= Gas Volume= Air volume approximately

Solving the equation

V= 4227 m^3
