im confused?

Question

a graduated sylinder has 50.2 cm of water and a rubber stopper added makes the water level 55.2 cm
the rubber stopper weighs 15g
the density is 3g cubed
if the rubber stopper was cut in half wut would the density of one of the halfs be?
(i think this is a trick question because if you cut it in half and put it in the water the water level will rise by 2.5 then you have to divide 15g/2.5 and you get six double the amount of the normal stopper so im confused here)

Answer 1

I don't think halving it makes any difference because don't you have to half the mass because you half the stopper (therefore it would be half the grams making it 7.5 grams) if thats so you would divide 7.5 by 2.5 cm since it probably would only rise half the distance as it would normally and you still get the same density of 3.

Answer 2

The only change in density here is the question:)
Density is a property. The amount of a substance will not effect the density. If you cut the rubber in half, you would expect the displacement of water to be half as much since the mass is cut in half. However the density will not change.

Answer 3

The density of the halves are the same as the density of the original rubber stopper. Density is mass over volume. There is half the mass and half the volume, so it comes out to the same thing.

Answer 4

If you cut it in half the density would be the same, but it would displace half as much water because it takes up half as much space.

Answer 5

the density would stay the same density does not change when you cut something in half
