How can you use the density of an object to predict whether it will sink or float?
Bas_tet [7]

Answer:

Explanation:

If an object has a higher density than the fluid it is in (fluid can mean liquid or gas), it will sink. If it has a lower density, it will float. Density is determined by an object's mass and volume. If two objects take up the same volume, but have one has more mass, then it also has a higher density.

Answer:

Explanation:

Given

mass of water molecule m=2.99\times 10^{-26}\ kg

mass of person M=62\ kg

It is given that body is mostly made up of water

suppose n water molecules constitutes 62 kg

so n\times m=M

n=\frac{62}{2.99\times 10^{-26}}

n=20.73\times 10^{26}\ kg
