We had to find out the densities of 5 'unknown' substances, but now I need a table of known densities so I can compare my answers with ones in the table so I can find out which one's what.
I seem to be unable to find the table of my likings, does anyone have a good one?
My findings:
1: 1.29g/cm3
2: 9.3(33333)g/cm3 (seems to be some sort of wood, look at pic, maybe oak?)
3: 0.9g/cm3
4: 8.4625g/cm3 (my best guess is brass)
5: 7.33g/cm3 (so far I think it's "Manganese")
Most are rounded off.
