At what depth in sea water is the mollusk located if the pressure of 751.9 kPa acts on it from the side of the water.

Initial data: P (pressure that acts on the mollusk from the seawater) = 751.9 kPa (751.9 * 10 ^ 3 Pa).

Reference data: ρ (density of sea water) = 1030 kg / m3; g (acceleration due to gravity) = 9.81 m / s2.

The depth at which the mollusk is located can be expressed from the formula: P = ρ * g * h, whence h = P / (ρ * g).

Let’s make a calculation: h = 751.9 * 10 ^ 3 / (1030 * 9.81) = 74.41 m.

Answer: The mollusk in sea water is located at a depth of 74.41 m.
