**1. The problem statement, all variables and given/known data**

The deepest point in any ocean is in the Mariana Trench, which is about 11 km deep, in the Pacific. The pressure at this depth is huge, about 1.13 108 N/m2. (Take the bulk modulus of seawater to be 2.34 109 N/m2)

(a) Calculate the change in volume of 1.2 m3 of seawater carried from the surface to this deepest point.

(b) The density of seawater at the surface is 1.03 103 kg/m3. Find its density at the bottom.

**2. Relevant equations**

B = changeP/(changevolume/Vinitial)

or change_volume = Vinitial(change_p)/B

**3. The attempt at a solution**

im not sure if for part a i just plug in the numbers they give..im getting like .0579 m^3 but that's wrong

any help?
