Physics (?) Question

How would you go about calculating how much helium would be required to lift a certain weight and by extension what volume of space is required to enclose the helium?

I assume this amount of helium required would vary with altitude so let's set the altitude at 1000m. To help me work out other things could whoever is good enough to show me how to do this do it for an altitude of 2000m also. The weights should be 1k and 10kg.

Also what value of hyrdogen would i need to do this for hydrogen?

Thanks.
