A piece of metal weighs 72,0 gram. We have a cup with water at 20 degrees celsius on a scale. the scale is reset and the piece of metal is lowered into the cup, without it touching the sides of the cup. the scale is now on 10,0 gram. what is the density of the piece of metal.

We think you’ve probably forgot the volume of water in the cup and we haven’t really studied density yet.
Bye^^
Oh? We were told that you knew about Archimedes?
Then you really haven’t got any chance to solve this problem.
Don’t know if we should do more about this?
density= mass of metal on mass of water = 72.0/10 = 7.2
