Question

You have a 100.0-ml graduated cylinder containing 50.0 ml of water. you carefully place a 190-g piece of brass (density = 8.56 g/ml) into the water. what is the final volume reading in the graduated cylinder?

Answer 1

So find how what volume the brass occupies
so we divide the mass by its density so: 190/8.56 = 22.196ml

since there is 50ml already  in the cylinder add that volume to the water: 50+22.196 = 72.196ml

hope that helps
