If a sample of pure calcium 9Ca) contains 4.69 x 1022 atoms of iodine, there are 0.0779 moles of calcium in the sample. The correct answer will be A.
Answer:
It will sink.
Explanation:
Density of water=1gm/cc (In CGS)
Volume of cube=l^3 =3^3= 27cc
Mass of cube =54gm
Density of cube=M/V =54/27 =2gm/cc
Here, density of cube is greater than that of water. So, the cube sinks.
