How much more matter is in a gram of osmium than in a gram of uranium?

[–] [email protected] 2 points 7 months ago* (last edited 7 months ago)

Given that mass behaves the same regardless of what is providing that mass in a gravity field, I imagine it simply the ratio of the weights. I’m assuming NewtonIan physics here.

Osmium is 22.59 g/cm3.
Uranium is 19.1 g/cm3

I would therefore expect about 10% more energy if it was made of osmium, simply equating mass and energy here with the famous crazy-haired guy equation.
