# How many balloons?

Given that helium rises, how many balloons would say a 150 pound person have to have (how much helium?) in order to be be picked up off the ground. I suppose the number of balloons would also help change HOW FAR the person gets lifted off the ground? Does this relate to acceleraction and/or force of gravity?

To work this out you need to know the volume of each of your helium balloons, and then know how light a volume of helium is compared to the same amount of air.

Then when you know the mass of the person and those two amounts you can calculate the mass that can be lifted by a given volume of helium, which is the relevant factor here.
