Is there any easy way to determine the charge on a van de graaff generator based on the voltage?

If you could determine the capacitance of the dome, you could use the relationship involving Q, C and V.

The capacitance of a sphere in picofarads is very roughly equal to its radius in centimetres. Of course there will be an exact formula on Google. Then Q = CV (suggest microcoulombs, picofarads, megavolts)
