The velocity of sound in sea water is 1533 m/s. find the bulk modulus (in n/m2) of sea water if its density is 1.025 ´ 103 kg/m3.

The speed of sound in a medium is given by:

where
Ks is the bulk modulus
is the medium density

In our problem,  and , so if we re-arrange the previous equation we can find the bulk modulus of sea water:

An atom that has fewer electrons that protons is called a positive ion.
