I got an A on my science fair checkup! thanks so much

of volume*

d = m/ v mass per unit if volume

can I have an equation to find the mass of the helium? then using that, find acceleration

It's a science fair, I am see'ing the effect of helium on a balloon in air

I found out a better way to ask the question. Do you know of a way to calculate acceleration as a function of density?

to find the mass I need the weight, I don't have the physical balloon, how can I figure out using the percentage of helium as a variable how much it weighs? then I can multiply times 9.8 and get the mass? I think it was a mistake taking a.p physics, it is so tough for me

Homework Statement I have a balloon with helium in it, I need to know the acceleration that it rises. It would be great if you could tell me what I need if I am missing any. This is what I have, Density of liquid(air) = 1 g/l Density of Helium = .1786 l/g Volume of Balloon = 91 cubic...
