Answer:

1. One is more compact than the next hence more density

2. A: 0.67g/cm3 hence will sink

B:0.56g/cm3 hence will sink

C:0.91g/cm3 hence will sink

Explanation:

Use the formula mass/volume to find its density with S.I unit is g/cm3

And to determine weather or not it sink use the relative density formula

Density of substance / Density of water
