Can someone please maybe tell me what the spesific gravities for H2SO4 98% and HNO3 98-100% is?
I do have some values in a text book but not for these persentages.

Well if I remeber right Enigma told me that 100% H2SO4 has a spec. gravity of 1.84 g/ml

This is great information. I erred in thinking that specific gravity was linear. The more you know the more you know you don't know. :-)
