In the Challenger Deep of the Marianas Trench, the depth of seawater is 10.9 km and the pressure is [tex]1.16\times10^8[/tex] Pa (about [tex]1.15\times10^3[/tex] atm).

If a cubic meter of water is taken from the surface to this depth, what is the change in its volume? (Normal atmospheric pressure is about [tex]1.0\times10^5[/tex] Pa. Assume that for seawaterkis [tex]45.8\times10^{-11}[/tex]/Pa.)

2. Relevant equations

I assumed that [tex]\rho_0V_0=\rho V[/tex], but that is not true. So, I don't know what to do.

3. The attempt at a solution

The above was my attempt, resulting in a change in volume of 0.091 m^{3}, which didn't work.
