Thanks Ian.

i read, "To achieve approximately 700 grams of free lift, a 100-gram
 balloon  will  take  about  40  cubic feet  of helium. To achieve 900 grams
of free lift, a 300-gram balloon will need about 70 cubic feet of helium."

Does that sound right?  If so, lifting a kg requires about 2 100-gram
balloons?
